Know people who are going to jail

Ok heres the story, I know two guys who are going to jail. One guy "S" is a long time mate of mine who recently started hanging out with me after not seeing each other in a year to smoke weed. He was homeless for a year and got busted for a few shoplifting charges and was given fines. He then got busted for shoplifting, was drunk and assaulted the security guard and has the court case pending. I haven't saw him in a month now until he came up to mine with some hash and a his mate, someone I knew from years ago, "K".

They said stoned that last Sunday they were up in a really posh part of our town picking magic mushrooms when they were picked up by the police, Apparently they fit the description of two guys who robbed someone's house in the area.

They said the court date is the day after boxing day. Basically, what I wanna know is am I breaking the law at all by having S or K in my house at any point? S, at one time never showed for a court appearance and came up to my house, but that was months ago,

I have to ask you G: why are you hanging around with the likes of S & K? when in doubt, assume the worst and that you are potentially putting yourself in possible trouble by association and proximity.
