Not gonna give you a life lesson but sounds like your 'friends' are putting you in situations you dont want to be in, anyway 2 options, take the rap, get a criminal record, get a rep, bugger your life up (well not so seriously) struggle to get a job (who wants someone who will steal from them? ) or option 2, tell the guy you have nothing to do with it, you dont have to tell him who stole it, say you know whos got it or where about it is etc, at the end of the day its all about your ass not others. If you dont have anything to do with it then theres no problem? Is a so called 'friend' worth a criminal record?
