> Banning research funding is a decidedly more political act.

Possibly but not probably. Once a situation becomes politically interesting any action or inaction could potentially be the more political act.

If only highly political actors are asking for more research then doing nothing is simply fiscal prudence and not an especially political act. I expect a lot of research on violence has already been conducted and the answers to any questions are probably already known. I don't normally see people in this debate saying 'we don't know X', they say 'we know X' and someone else says 'that is true but misleading/not important enough to justify Y/think of the children', etc.
