Pepper spray and high drama

So Jamie is still hanging around with his loser friends - something I didn't know until I was coming home from doing a little grocery shopping. There I amin the parking lot when I hear "hey Jamie's mom, Jamie's mom! Megan just pepper sprayed Jamie in the eyes!" Greeeeeeat.
Toddle off to the house I go (loaded with a shit load of heavy groceries) and I can hear Jamie yelling in the house. I dump the groceries and go upstairs and there is Jamie wearing only a towel with his whole face beet red telling me that Megan was trying to pepper spray his shirt and hit him in the eyes instead. Megan I should mention is 18 and has bad influence written all over her - she is the one who provides the rest with their pot and has a mouth that she really needs washed out with soap. Needless to say, I am NOT amused because as far as I know pepper spray is illegal unless you are a cop. Well, armed with this information, I head over to her house because I really think that her parents need to know what the hell the little bitch is up to. When I get to the scuzzy apartment building and buzz up she tells me that she is coming down and will talk to me. She informs me that she lives alone and that spraying Jamie was an accdent so I should just let it go. Let it go - she just sprayed my son in the eyes and I should just shrug my shoulders and say oh well. Then she tells me that she came into my HOUSE - I've already warned her not to come on my property because of an incident that happened at the beginning of the summer. Megan feels she has no responsibility for the the incident and that Jamie shouldn't have been in the way of the papper spray. Like Jamie doesn't have enough problems with his eyes - cripes he's had surgery once, had an eye patched for almost 4 years and has worn glasses since he was 2. I'm so paranoid about his eyes that this just sent me over the top. Then this little bitch tells me that I don't know my own son and that I TREAT HIM LIKE A DOG!!! oooooooooooooo last straw. Stomping home I come, fuming. BT is freaking that that little bitch had been in the house, the dog is barking and Jamie is still whining. I've had enough - I call the cops and they say they will send out a car.
Time passes - three hours to be exact. Finally, the cop shows up, listens to the story and tells me that pepper spray is NOT illegal since they sell it to hunters for bear protection but he would go to the scuzzy apartment and talk to her and her father (who she lives with) and warn her about the pepper spray. BT is furious that we can't charge her with trespassing for coming into the house without permission and the fact that Jamie was protecting Megan to the cop when Jamie had tried to get ME in trouble with the cops not even two weeks ago.
I was ready to just collapse after the cop left, I was just soooo exhausted but BT wanted to rage awhile bout the cops. lol He's convinced if Megan had been a GUY then the whole thing would have gone down differently - in BT's words "it's a woman's world".
Then last night, Jamie comes flying in the door and says "Evander's father wants to talk to you." Evander? Who the hell is Evander" (and btw, who names their kid Evander??) I come to the door and there is this TROLL of a man who immediately starts threatening Jamie and probably would have been yelling at me too if BT hadn't been standing behind me at the time. I can't believe this man threatened to beat Jamie up and then throw him in his TRUNK to take him to the police station because Jamie supposedly threw a stone at his son. God I need to move.
