First off, how are there two people involved in shootings IN DETROIT who have carry licenses?!?!
I thought that was a VERY tough city to get a permit in.
If the information given is correct, both men should be charged as neither of them took the responsibility for what the CCW License is really for.
This Permit/License is not for "Street Justice". Once you start chasing someone, especially a person that is no longer on your property, you pretty much lose any right to claim "Life Endangerment" and thus you will be promptly screwed in the eyes of the law.
There is no doubt that emotions carry sway and none of us can say what we would or would not be able to do - but facts are facts.
If you carry a weapon, you have a responsibility to carry it for the right reasons and to exercise restraint.
In these examples, it would appear that was not the case.
