They're targeting these guys for assasination for things they might do, or are suspected of doing in the past. It's not like they catch them in the actual act of committing terrorism.
So to satisfy your Strawman it would be the equivalent of finding a bank robber months after the robbery inside his house, and the police blowing it up with his family inside to get him. I don't think that would fly in any reasonable society

Edit: Interestingly here is a RL example that happened today, terrorists caught robbing banks, beaten by the cops then mugshots digitally altered so nobody would see the wounds http://www.guardian.co.uk/world/2013/feb/04/greece-police-lo...
