I'm a minor (15), and I was recently cought with 3 eights of marijuana on me, 
and i was wondering what type of sentence i am facing?  If you know of a 
better news group to post this to, I'd appreciate it also.  Should I get a 
lawyer or just stay with a court appointed attorney.  I've had a lawyer tell 
me he could get me off, but I would rather not spend $400...  I was charged 
with only possesion (not intent to sell).
On my record I already have retail fraud ][, and a curfew violation, so it is 
a first time drug offence.
The atened me that if I did not give him the bag, and if he found it, that he 
would hit me.. In my condition at the time I believed him, and therefore gave 
it to him... If I was straight I would have probably none better, but I've 
been told that this is assult and that I could have the charge against me 
dropped because of that.  Is this true, and if so, would I need a great lawyer 
to make sure the chargers are dropped?  I'd think that it wouldn't be that 
hard for a cop to lie about that... 

Thanks in advance..
