UPDATE: Conservative MP Larry Miller retracted his comments comparing Liberal support for the Gun Registry to the policies of Adolf Hitler and the Nazis after Question Period Tuesday.

Miller called the references "inappropriate."

His retraction, however, did not satisfy interim Liberal leader Bob Rae or MP Justin Trudeau.

“Anybody who raises the name of Adolf Hitler in a debate always loses … It’s a ludicrous, ridiculous, cheap, horrible comparison,” said Rae after Question Period, according to The Globe and Mail.

Trudeau tweeted that Miller's apology was "weak and insincere" and made it sound like he was apologizing to Hitler.

Weak and insincere apology by Larry Miller. It sounded like he apologized to Hitler for using his name. Didn't apologize to Allan Rock.

As the Tories make the final push to scrap the federal long-gun registry, one Tory MP has compared Liberal support for the database to the policies of Adolf Hitler.

Conservative MP Larry Miller (Bruce-Grey-Owen Sound) made the comparison in the House of Commons on Tuesday.

Miller first drew on former Liberal Senator Sharon Carstairs statement that “the registering of hunting rifles is the first step in the social re-engineering of Canadians,” to link Liberal policy to Nazi social engineering. “Mr speaker, that is what Adolf Hitler tried to do in the 1930s,” Miller said.

“The long-gun registry is at its core solely about an idea that the Liberals of the 90s had that guns are inherently evil and must be taken out of the hands of the general population," he continued. "Again, who does that sound like?”

Miller then went on to liken former Liberal justice minister Alan Rock to Hitler for stating that guns should be given only to police officers and soldiers. See the clip for yourself below.

Also on Tuesday, the Tories moved to limit debate on getting rid of the registry. Government House Leader Peter Van Loan has said he wants the bill passed by mid-February.

The government wants to scrap the registry because it says it is a waste of money, ineffective at improving public safety and preventing crimes and it targets law-abiding gun owners instead of criminals. Getting rid of the registry means getting rid of the information in it, the government has said in defending the move to destroy the data. About 7.1 million non-restricted firearms were registered in the database as of September.

• What does this new bill on the gun registry do?

  We keep hearing about scrapping the long-gun registry, but really what we're talking about is scrapping the requirement for people to register their rifles and shotguns - that's what Bill C-19 aims to do by making amendments to the Criminal Code and Firearms Act. Once passed, people will not have to register their non-restricted or non-prohibited firearms. It also provides for the destruction of existing records in the Canadian Firearms Registry for those firearms. <em>With files from CBC</em>

• What exactly is the registry?

  It's a centralized database overseen by the Royal Canadian Mounted Police that links firearms with their licensed owners. It contains information about all three types of guns that must be registered - non-restricted, restricted and prohibited. (All firearms must be registered.) To register a firearm, you have to have a licence to possess it.

• Does the bill make any changes to licensing requirements?

  No. Canadian residents need a licence in order to possess and register a firearm or ammunition and that won't change. There are a couple of different kinds of licences because of various changes to laws and regulations over the years.

• What are long guns?

  There are three types of guns under Canadian law: non-restricted, restricted and prohibited. Most common long guns - rifles and shotguns - are non-restricted but there are a few exceptions. A sawed-off shotgun, for example, is a prohibited firearm. A handgun is an example of a restricted firearm. Different regulations apply to different classifications of firearms.

• How many guns are we talking about?

  As of September 2011, there were about 7.8 million registered guns. Of those, 7.1 million are non-restricted firearms.

• Why does the government want to get rid of the long-gun registry?

  The government says it is wasteful and ineffective at reducing crime and targets law-abiding gun owners instead of criminals, who don't register their firearms.

• Who wants to keep it?

  Police and victims' groups are big supporters of the registry. Police say the database helps them evaluate a potential safety threat when they pull a vehicle over or are called to a residence. They also say it helps support police investigations because the registry can help determine if a gun was stolen, illegally imported, acquired or manufactured. This year, the RCMP says police agencies accessed it on average more than 17,000 times a day.

• When will the registry cease to exist?

  The government has passed the legislation and the registry no longer exists. Except for in Quebec, where an ongoing court challenge means the owners must still register their guns in the province.

• Why does the government want to destroy the records?

  The government is doing this to ensure that no future non-Conservative government can recreate the registry. Public Safety Minister Vic Toews has also made it clear that if any province wants to set up its own registry it would get no help from the federal government. The Conservatives are so fundamentally opposed to the existence of the records, because they say they focus on law-abiding citizens instead of criminals, that they don't want them available for anyone to use.

• How much does the registry cost?

  The registry cost more than $1 billion to set up in 1995 and the cost was the source of much controversy. Public Safety Minister Vic Toews said on Oct. 25 that the government's best estimate is that it costs about $22 million a year to operate. That's the entire registry, not just the long-gun portion, but he noted most of the guns in the registry are long guns. He said he didn't know how much money scrapping the requirement to register long guns would save the government. Conservative MP Candice Hoeppner says there are also "hidden costs" that are borne by provincial and municipal police agencies to enforce the registry.
