Nice youtube video, if it actually pertained to the subject I would have paid more attention.
Cpl Mike Roberts, shot and killed by Huberto Delgado was done with an AR-15, not a pistol, meaning whether he had a CCW is irrelevant. He shot the guy with a rifle, which just about ANYONE can get their hands on. In the context of CCW causing more or less death, this death is irrevelvant to the arguement.
James Wonder, the 65 year old who shot Officer Pettit, was FOLLOWED into a parking lot after a road rage incident (both drivers yelling and making obsene jestures). Officer Pettit, followed Mr Wonder into a parking lot, and BLOCKED Mr Wonder's car. He then got out of the car and confronted Mr Wonder. Due to the man's size and age, Mr Wonder (who was 65 at the time of the altercation), felt there was a legitamite threat to his life. Remember Florida has STAND YOUR GROUND, he was not obligated to hide in his car. Case hasn't gone to trial yet...
3 Pittsuburgh officers shot by Richard Poplawski, were gunned down with an AK-47. Poplawski was lying in wait, armed and armored, for those officers. He didn't walk up to them in the street with a concealed handgun, he used a rifle in his home to shoot those officers. Same as Huberto Delgado (see above), CCW license is irrelevant again, a rifle was used.
Christina Korbe, killed the FBI officer. Again not a CCW issue, as she shot and killed him in her home. The FBI agents and police broke down the door to her home serving a warrant. Her claim is that she didn't know that there were officers in her home. When she walked out to the top of the staircase, she saw intruders coming up toward her children's room. She felt that there was a legit threat to her kids and shot once at the intruders. She immediatly called 911 and told the dispatcher she thought she shot an intruder in her home. Again, doesn't appear she knew law enforcement had entered her home.
I'm not disagreeing that these deaths are tragic, they are. But in the context of stating that CCW is "bad", this video holds no weight as many of the instances are NOT of CCW use.
