“If you were in this store while this happened and you drew a firearm you would have been absolutely wrong.
(I am assuming that the youths entered, removed property, and left the store).”
An interesting post, bringing forth numerous avenues of discussion.
What if the person in the store was white, elderly, and in fear of serious injury or death at the hands of a mob of criminal blacks?
Factor in the Americans With Disabilities Act and legislation regarding abusing the frail elderly and your reply may not be as accurate as you assume.
In light of what I have briefly mentioned, may I ask what would you think about those factors?
If they didn't talk to you or threaten you or approach you in any way, then I don't see it. If they attempted to remove property from your person, then all bets would be off and that's a robbery, which is an inherently violent act. Draw away!
