Me and my friends and my brother went to wal mart and they took a helicopter and I was a look out and now I have to go to court what should I do even though I was the look out and the other 2 where 18 and 12 what should I do even though I was a look out and nothing else and I did not even steal that day... what should I do??

You actively took place in the crime... by your own admission.

What did your lawyer tell you to do?
