Wow !!
What a crazy. They should call this site "Criminal Advise" instead. hehehe
They gave you all the advise you asked for. Yes, you have to tell the truth if asked by the police or you can be arrested.
Do you know "for sure" what your friend is wanted for? Maybe theres more to it then you know.
Your friend's a wanted criminal, and you want help on preventing the police from finding him.
Your other friend has a very very messy house and never cleans it.
Tell us about all of your other friends, so we'll have more to talk about, so we don't have to talk about Jacob anymore.
