Woman sues bonding firm, claims search went too far

Does anyone have a reasonable explanation of why bonding company agents are allowed to act like ATF agents in the worst nightmares of right-wing nuts? I keep hearing these stories, but nobody ever does anything to stop them. The best anyone can come up with is a Supreme Court decision from 1872. So because bounty hunters were allowed to roam wild during Reconstruction, they can break into my house and threaten to shoot me if I don't tell them where someone is? Does this make any sense to anyone?
