We have enough necessary I believe.
We have cameras (one pointed to the place where a fat kid took down the fence and people went into that apt. complex and smoked), we have an SRO officer, that's about the extent of it, though I am probably leaving out a few minor details.
My school is full of pussies and smokers anyway, and the people who DO deal drugs tell EVERYONE to make them seem OMIGOSH SOOO BADASS so they are pretty much at the mercy of whoever chooses to snitch on them. It's a wonder, with the mouths these kids have that they all aren't in jail. (Personally I think bringing drugs on a government institution is a stupid idea anyway)
As for vandalism, eh, we don't get much. Couldn't tell ya why, we just don't. We have the bathroom graffiti and the occasion "OMG I'm soooo badass" spraypaint graffiti, and the occasional pussy fight, and every once in a while some dumbass will pull something stupid, but other than that we don't have any real gangs in the area, so minimal crime=minimal need.
