I spoke to a police officer about this a few years back and he asked me: Do you provide him shelter and food and are you his legal guardian and of course I said yes, both my h and I are and he said that because he was underage I really could not do that.
Really, when you think about kicking out a 17 year old kid, where is he going to go? This economy sucks and for a kid to be out on his own (could be a good life lesson BUT...) it's it is your choice.
Your son will get thru this phase but it will take some time.
