Getting killed is one of them. Wounded is another. And starting work when you don't know if you'll come back alive is bound to raise your stress level.
All this for an annual salary that is sometimes less than the cost of a semi-luxury car.
So are we surprised that five New York cops are among the dozen people arrested in a gun smuggling sting operation? No, and yes.
There have always been corrupt cops. Just like there are and have always been corrupt people in any walk of life.
But cops are supposed to be different. They are sworn to uphold the law. And so it's especially disturbing when the laws they're accused of breaking involve selling weapons to people who will likely commit crimes with them.
The specifics: The cops are accused, along with others, of transporting stolen slot machines, weapons (including three M-16 rifles, a shotgun, 16 handguns), stolen cigarettes and counterfeit goods. The street value of the hauls: more than $1 million.
We'll have the latest on the busts - and reaction, at 11.
Also at 11, electronics are, once again, expected to be some of the hottest gifts this holiday season. And there appears to be real bargains out there. But how do you know for sure? Consumer Reports tonight takes a closer look.
We'll also have any breaking news of the night, plus Meteorologist Lee Goldberg with his AccuWeather forecast, and Rob Powers with the night's sports. I hope you can join Sade Baderinwa and me, tonight at 11.
