Brian, I used to be a Bail Agent. Yes you can go get the bad guys in their home without a warrant. You have more rights then Police Officers do. It is a very interesting job. Lots of time spent tracking the people down, lots of time spent on stake outs. Most came without a major problem, but the others made you earn your money.
We always tried to be professional. We let them know that it was only business and if they went along with the program they would be treated with respect. If they didn't, we could (an did) make them real uncomfortable. As great as it would be to only go after the big bail amounts, you had to go after the little ones too. The little ones most times took more time and effort than the big ones. You had to try and get them all or the bail bondsman would find someone who would go after all of them and then your out of a job.
It's kinda like the last of the wild west. Very dangerous at times but rewarding. After all, you are hunting the most dangerous animal of all, Man.
It is not a glamorous as it seems. You spend too many days and nights away from home. You can make good money, but it comes at a price.
Best to ya, John K
