Profile of a snatch shot photographer

What kind of photographer takes `snatch shots’,  or  photographs of people that are taken without their  consent?

I’ve taken quite a few of these pictures for various newspapers and magazines and I think I was motivated:70% by the urge to make money, 20% by  the thrill of the chase,  and 10% by the belief that I was doing the right thing.
But in legalised snatch shot photography, defined as when governments or police departments practise it, the motives are probably different.
At a guess, they are motivated 70% by the belief that they are doing the right thing, 20% by the thrill of the chase and 10% by the urge to make money.
One reason for the 70% contrast might be financial status. Most freelance photographers are self-employed, they need the money.
Government and police snatch shot photographers are employed, they get paid whatever happens.
