A friend of mine was arrested for Intent to distribute marjuana, Felony Theft By receiving,Firearm/Knife during a Felony,Participate in criminal street gang activity, tampering with evidence, Obstruction of a officer, concealed weapon and had a stun gun and a taser....he also has criminal attempt in which he was indicted on two days ago...The only part of the story i got is he tried to Rob a drug dealer but wuznt successfull im guessing thats where the attempt charge comes from. we live in Georgia he is 20 and he was arrested twice as a Juvenile but i think this is his first adult Arrest. how much is my friend looking at.
