Many red states have passed anti-Sharia Law legislation because of fear that some foreign and possibly harsher law/justice would imposed on the citizens of the US. Never mind that it can't because of the Constitution and that those wanting harsh Biblical law imposed are extremest Christians (Dominionists) in the US, who already have a plan to do away with the US Constitution if they get into power and impose Biblical Law (which it currently couldn't because of the Constitution).
If we as a society allow extrajudicial punishment/capital punishment in the form of "Stand Your Ground" laws for crimes such as stealing, then our penalty for crimes, such as stealing is by default harsher than the penalty for stealing under Sharia law.
As said by many before, "Stand Your Ground" laws make us more violent. For the one left standing, tells the tale of what happened.
And it may not be the truth, but a self serving pack of lies. But if you can get away with it, because apparently claiming "Stand Your Ground" means that there will be no investigation (especially if you are white killing a non-white), why not!
It's a white "get out of jail free" card with black lettering.
