Let us say, there is a tower block. In which, is the headquarters of an organisation. This tower block lies within an area where if not direct support of said organisation, local sympathies are at the least neutral. The tower block is also home to an indeterminate number of civilians.

This organisation has been staging attacks on your state. Bombings, kidnappings, etc.

What do you do?

Bomb the building? Send in troops to target only the HQ? Ignore them and let them get on with their merry bomb-making?

Completely unrelated to anything going on at the moment... honest.
