USB Disabled

I disabled the three USB ports on my laptop so that my son can't put more porn onto his PSP. Last night I went to get a drink of water before going to sleep. My son was busy accessing porn on the internet earlier that day. When I finished my water I came out of the kitchen to tell him to get off ther internet. He was busy transferring it to the laptop so he could look at it. I watched him for a moment and confronted him. He shut everything down really fast. I told him that I saw what he was doing and that I am disappointed in him. He said he wasn't doing anything and started to swear at me and call me names. I said let me see what is on there, he refused. He called me more names and swore at me some more. He called me a fucking liar and asked me how he was to prove it. I said, "it is simple, let me see what is on the memory card.". He called me a stupid fucking bitch. I told him that he was not allowed to hook anything up0to the computer anymore. I am not going to enable to USB ports and pretend that I don't know what is wrong with it.

This morning, I went into his room and I looked at the pictures on his PSP and there was tons of porn on it. I will erase the card tomorrow if it is still there. What is he going to do? Accuse me of erasing it? Ha Ha Ha I will get the last laugh! He won't ask me about it because, after all, what is he going to say to me? What did you do with my porn?? I will get the last laugh.
