FBI acts like 50% of the people out there are criminals, etc. No way you should be infringing on the rights of 99% of the population just to have a crack at the other 1%.
We have the largest, both per capita AND total, population of prisoners of any other country in the world. We have so many laws on the books that it is impossible for anyone to go about their lives and not break some obscure law, even judges.
The US has a full 25% of the entire worlds prisoners yet we are only 5% of the population. At any given time 3ish% of the population is in jail, on parole, or probation. Either the US population has an absurdly huge predisposition to being criminal assholes or our justice system is fucked, I'll let you come to your own conclusion...
So technically they are more right than you think...
