Q for women, your thoughts on this?

I'm a guy, and I don't think this was fair at ALL! Friday I went to the supercenter to look at some electronics, mini stereos and speakers, stuff like that. So I went to the electronics section and saw the CRAZIEST sh**! I was in an aisle, and there was 1 boy at the end of the aisle, he was going through DVD's at that end. In the middle of the aisle, was this she looked like a business woman I guess. She was in her 40's I guess, had on this multicolored dress and a short sleeve top. She was mabe 5'4 and 150 I guess. The boy was shorter than her by a little bit, skinnier, and had this big shirt and baggy shorts on. Now I never saw a customer service guy the whole time in that section, I dunno where he went to. I didn't see what the boy was doing at the end of the aisle, but SHE did! He was trying to lift DVD's, rip em off. She sees him doing it, walks up to him, and tells him, "Put those back, I know what you're doing, put em back." He says to her, "Mind your own business, bit**!" Then he tried to go around her, but she stepped in front, blocked his way and said "You need to put those back, NOW." He tried again to go around her but she stepped in front the other way too, blocked his way again! So tried to push her, but she's taller/heavier than him so she didn't move hardly at all. He went to swipe at her/sort of shover, and their arms got tangled up, but not for long! It happened like 1,2,3! She ends up behind him, wraps her arms over his upper body, trips 1 of his feet so he falls forward and eases him down to the floor on his belly. So when he's down on the floor face down on his belly, she puts his hands behind his lower back (not hurting him, just holding them there), puts 1 leg over his hips, and sat down on his thighs!!! Man, he was PISSED! He tries pushing her off his legs. Uh uh, NO chance! He yells, "get off my legs bit**, get off me!" but he can't move. I was shocked! She had NO trouble at all doing that to him! He was helpless. She looks at me and said CALMLY, "Would you get security for me please?" And I just looked at him, sat on by her, pointed at her, and she said, "Don't worry, I've got him!" and smiled! That comment pissed him off more, he cussed her out again and tried again to push her off his legs. Nope! Not gonna happen. She told him, "You need to calm down." I couldn't believe how calm she was! So I left, took me about 2 minutes to bring the security guy back. We get back, and now the boy has a TOTALLY different attitude! He's CRYING!!!!! And telling her, "please, get off my legs, i'm really sorry ok? i didn't mean to." and crying! he wasn't trying to push her off him anymore! So the guard looks in shock, then smiles. She let him have his hands back, got off his thighs, and the guard asked her a few questions and took the boy away. I asked her how she did that? She said she's a paraprofessional. I told her I dunno what that is. She said she teaches in a classroom for kids with behavior problems and in her job, she gets trained how to restrain kids who get out of control, and that's one way she does it, she's had to do it before. WOW! But really, I don't think it was fair for her to humiliate him like that. I mean, once she sat on him, he had no chance, he couldn't move! That wasn't really fair to him. But, what do you think? Was she right to do that to him, sit on him like that? Should she be applauded for doing what she did?Q for women, your thoughts on this?
I feel like as soon as the kid got physical with her, ie trying to push her, she had every right to fight back even if the kid have no chance. LOL I cant believe she would do that. JW what state did this happen in?
