Iraqi security forces have had a growing impact on terrorist operations. This largely goes unreported, but the Iraqi police and soldiers, especially the elite counter-terror units, have interrupted many terror attacks, and arrested many terrorists. Aware of the corruption of the courts and regular police, the counter-terror units will often just kill key terrorists during raids, rather than risk the prisoner bribing his way to freedom. This is also an unofficial policy in some American operations, and official policy when missile armed UAVs are used.
We get enough intel and the risk of further friendly casualties is far enough above zero that we're just killing people out of hand when in the past we might have sought to capture them. Congratulations lawfare participants in the media and legal professions. Their blood is on your hands.
