order of protection

my step son's (now) ex co worker (female) had called him up asking him to pick her up at a bar because she was too intoxicated to drive home (probably a good thing), so my step son having a good heart, (not always thinking with the right brain) went to pick her up and took her back to her place, she had invited him in for some alcoholic drinks (he's over the age of 21) and he was there for a couple of hours and she decided she wanted another male co worker (over the age of 21) for some alcohol and sex) so she tells my step son to leave, and as we've always told him call us to come and get you if you're too drunk to drive, and before he could she called the cops and he was arrested for criminal trespass to land and he was going to call us but the arresting officer knocked the phone out of his hand and the other male that was there gave my step son back his phone and now there's an order of protection against my step which the day my step son got out of jail she was already texting him
