From what I hear, my high school has evolved quite nicely since I've last attended it 4 years ago. This is not an exageration either. They have over 100 cameras covering every angle inside the school and in the parking lots. Nothing more than the little logos over your heart that some shirts have is allowed (AKA, plain ass t-shirts). If you are absent more than 20 days, you aren't permitted to "graduate" to the next grade. I can't remember them all, and this was from what I've heard over a year ago, so I'm sure more paranoia has ensued.

BTW, the whole camera spleel is because when I went to high school we would literally have like 40 or so bomb scares a year, and after the whole Columbine incident happened my Senior Year (I believe it was then, or maybe Junior), they tightened the whole security 100 fold.
