I have goten a few questions on if Tennessee has a "Stand your ground" policy. As I recall I am pretty sure we do have it in Tennessee.
Now, to the entire Zimmerman thing in Florida I have no comment on the possible guilt or innocence of the people involved. Time and a jury will hopefully be able to find the truth.
As to the "hoodie gate" issue. I am sorry but people wearing pulled up hoodies do appear ominous and I don't care what color the person is. If I saw a person in A pulled up hoodie (especially in the summer in Florida) I would fear the person was trying to concele their identity for some nefarious reason. Seldom a good thing. There is a reason banks tell customers that hats and hoodies are not allowed to be worn inside the bank. It is not because they have some deep seated closet racism in their heart. It is because hats an hoodies obstruct the view of to a persons face and as to who a person is. A common tactic of criminals.
