needs to be change,too many innocent peoples are getting killed. they are taking law in there own hand.911 was called, by offender.,but he took law in his own hand.instead of listen to 911 operator. not to follow.if gun law was different.,he would not have been so quick to shoot an unarmed 17 yrs old.advised he feared for his life,when he had the weapon..an excused to use his weapon base on Fla law.an unarmed person is not safe.
