I really can’t provide any help regarding your legal situation because, frankly, I can’t make heads or tails of what you wrote. As an “ill time student,” you might want to concentrate a bit more on punctuation, grammar, sentence structure, and comprehensible writing.
Generally speaking, trespass 2nd is a valid charge for being in a park with posted hours after those hours – especially if you had to jump a fence to get there. With what little info I can glean from your gibberish, I don’t see any argument to that charge. Obstructing is similarly a valid charge for running from the cops. Both charges are gross misdemeanors. While jail is possible, depending on your prior run-ins with the law, fines and probation are more likely. I noticed you specified that you have no criminal history IN WASHINGTON – what is your criminal history elsewhere? Are you a juvenile?
