Unless you work at very odd hours, you probably aren't out on the streets 24/7. You are most likely on the streets for 4-6 hours a day, which really isn't that big of a deal. As for checking smartphones, maybe, just maybe, when police are out protecting people they shouldn't be hanging on social media or playing games on their phones? If you don't want to "get caught" using a smart phone, leave it at your locker. About shitting, maybe there could be a mechanism to turn off the camera for few minutes, so you could do your bathroom stuff in private and there really wouldn't be anyway way to abuse it since you'd see from the context of the video what was going on, e.g. if you are approaching a suspect, then video cuts off for a minute and next thing we see is bloodied suspect then obviously the cop should get penalized for that.
