My mention of Trayvon was to point out that the three conditions outlined- if answered no- does not keep one safe. Random acts of violence happen all the time
Mostly because he forgot to list the fourth condition - "are you a young Black (or rezervation Native or some of the groups summarized as Hispanic, to be fair) male"? Oh, and obviously there are certain jobs etc that you might add.
I have no issue with gun ownership personally, but objective security is not, with a few exceptions, a valid argument for it.
