I have been noticing a guy on a bicycle buying drugs on my street. He rides his bike from wherever he lives and just waits in the road and a car will show up and they make the deal and go their seprate ways. I video tapped them,got tag numbers and the police say that they have to catch them in the act. I am getting very tired of this going on and police don't seem to care. Will I get arrested if I go out there with my AR 15 and attempt to arrest them? I live in Alabama.
