Any inconvenience governments can impose will eventually be abused as a tool of arbitrary punishment. Take, for example, the no-fly list and related watchlists, which are supposed to contain the names of known and suspected terrorists so they can be monitored and their movements restricted. From day one, placement on the list has been misused to punish innocent people who won't do what federal agents command. Now FBI agents caught abusing the system want qualified immunity to shield them from consequences as people they mistreated seek justice through the courts.
