Damaging human rights is itself a form of harm that should go on the other side of the scales from fighting "terrorism". Ferguson reminded people that in many places the average person on the street is far, far more likely to be killed by a cop than a "terrorist".

Terrorism and police brutality are both law enforcement problems, and the solution is the same: enforce the existing law, impartially, publicly and universally.

The additional problem of terrorism is trying to fight it in other people's countries, where the enforcement brutality is even more of a problem. If you count the Iraq war as "anti-terrorism", then the effect of US anti-terrorism has been to kill, injure, abuse or displace far more people than Al-Quaida. ISIS are more deadly still, but they should be regarded as a hostile state rather than a terrorist group.
