A family is in shock after a police shooting left a young man dead on a Toronto streetcar this weekend.

Sammy Yatim was shot just after midnight on Friday, following an alleged altercation with police.

Initial reports indicated that police had been responding to a call about a man with a knife on the streetcar near Dundas Street West and Bathurst Street, at the time of the shooting.

Yatim was taken to a downtown hospital with a gunshot wound. He was soon pronounced dead.

The victim's sister, Sarah, confirmed that Yatim was the young man killed on the streetcar and said that her family was in shock over what happened.

Sammy Yatim was 18 years old at the time of his death.

The slain man’s friends have posted their condolences on Facebook and Twitter.

The circumstances of the shooting are now being probed by Ontario’s Special Investigations Unit.

The SIU investigates all incidents involving police in which death or serious injury occur, or when allegations of sexual assault are raised.

Nearly 76% of murders in 2011 were committed with a firearm, higher than all but two other states. The Republican-dominated legislature has spent more time focusing on expanding gun rights rather than curbing them. One Missouri lawmaker, Rep. Mike Leara, recently introduced a bill that would make it a felony for anyone to propose legislation that “further restricts the right of an individual to bear arms, as set forth under the second amendment of the Constitution of the United States.” <a href="http://247wallst.com/2013/04/15/states-with-the-most-gun-violence/#ixzz2QdJ7jcTe" target="_blank">Read more at 24/7 Wall St.</a>

    <strong>Firearm homicide deaths per 100,000</strong>: 4.24 (13th highest) <strong>Firearm aggravated assaults per 100,000</strong>: 57.36 (16th highest) <strong>Violent crime rate per 100,000</strong>: 405.9 (19th highest) <strong>Need permit to purchase handgun</strong>: No <strong>Governor</strong>: Jan Brewer (R) Arizona ranked in the top 10 states for firearm deaths between 2001 and 2010, along with homicide deaths of women and deaths of children 17 and under in those years. In addition, 30% of guns used in a crime within the state were sold less than two years before the crime was committed, indicating a high likelihood of illegal gun trafficking. This was a higher percentage than all states except for Missouri. In March, Guns & Ammo magazine ranked the state as “The Best State for Gun Owners,” noting the state is one of just a few that do not require a license to carry a concealed firearm. Also, concealed carriers are not required to notify law enforcement of their weapon except during “lawful traffic or criminal investigation, arrest or detention or an investigatory stop by a law enforcement officer.” <a href="http://247wallst.com/2013/04/15/states-with-the-most-gun-violence/#ixzz2QdJ7jcTe" target="_blank">Read more at 24/7 Wall St.</a>

The state also ranked within the top 10 for homicides of women with a firearm, firearm deaths of children and law enforcement killings, all within a 10-year time frame. Recently, the Alabama Senate voted to ease gun restrictions. The legislation, if signed into law, would allow residents to keep guns locked inside their vehicles at work without fear of pushback by their employer. The legislation also would allow people to carry a visible pistol without being charged with disorderly conduct. <a href="http://247wallst.com/2013/04/15/states-with-the-most-gun-violence/#ixzz2QdJ7jcTe" target="_blank">Read more at 24/7 Wall St.</a>

    <strong>Firearm homicide deaths per 100,000</strong>: 4.22 (14th highest) <strong>Firearm aggravated assaults per 100,000</strong>: 80.47 (9th highest) <strong>Violent crime rate per 100,000</strong>: 606.5 (2nd highest) <strong>Need permit to purchase handgun</strong>: No <strong>Governor</strong>: Sean Parnell (R) In 2010, there were more than 20 gun deaths for every 100,000 residents in Alaska, more than any other state in the country. That year, the state had more 15 suicide deaths with a firearm per 100,000 residents, also more than any other state in the country. Between 2001 and 2010, there were nearly six firearm deaths among children 17 years old or younger per 100,000 children, also the most in the country. In February, Alaska’s House of Representatives passed a law that would exempt the state from new federal gun laws. Any federal agent who attempts to enforce the law could be charged with a felony. Despite its passage, the bill is considered unconstitutional since federal law is superior to state law. <a href="http://247wallst.com/2013/04/15/states-with-the-most-gun-violence/#ixzz2QdJ7jcTe" target="_blank">Read more at 24/7 Wall St.</a>

  • 1. Louisiana

    <strong>Firearm homicide deaths per 100,000</strong>: 9.53 (the highest) <strong>Firearm aggravated assaults per 100,000</strong>: 99.51 (4th highest) <strong>Violent crime rate per 100,000</strong>: 555.3 (7th highest) <strong>Need permit to purchase handgun</strong>: No <strong>Governor:</strong> Bobby Jindal (R) No state had a bigger problem with gun violence than Louisiana. Between 2001 and 2010, there were 18.9 firearm deaths — which includes suicides and accidents — annually for every 100,000 residents, more than any other state. In 2010, there were 9.53 homicides involving a firearm for every 100,000 residents, by far the highest rate in the country. In November 2012, nearly three-fourths of Louisiana voters approved a state constitutional amendment that placed a very strict standard on determining whether individual gun rights can be limited. Since the amendment was passed, a host of legal challenges have been filed against the state’s gun restrictions, including a challenge of the ban on felons to own firearms. The state received an F for its gun laws from the Law Center to Prevent Gun Violence. Among the reasons for the poor grade are the fact that the state does not require a waiting period for gun purchases or prohibit the sales of assault weapons or high-caliber rifles. <a href="http://247wallst.com/2013/04/15/states-with-the-most-gun-violence/#ixzz2QdJ7jcTe" target="_blank">Read more at 24/7 Wall St.</a>
