Do you support random roadblocks?
Because otherwise, the only time police stop a drunk driver is when they see him driving badly. And once that happens, I don't care why he was driving badly. Is it OK to weave from lane to lane because you're on your cell phone? Is it OK to run a red light because you're tired? Is it OK to cut someone off because you're eating while you drive?
All those are cases of actually doing something wrong. We already have laws against them. If that's not enough, if we want to pre-emptively arrest anyone who we suspect is more likely to do something wrong, then we need the roadblocks. And while they've got us stopped, they might as well check for unregistered weapons, in case we might go hurt someone. And they can check for fertilizer in case we might want to blow something up.
