The security cameras show the exit routes and safe rooms used by legislators and staff. If the Capitol was invaded again, the invaders would know where to go, instead of wandering aimlessly.

I'm not a fan of security footage deliberately falling in the hands of someone who helped stoke a terrorist attack. Releasing it to Carlson will do nothing but make it easier for them to be successful next time. It's pretty fucked up that a third of Americans support domestic terrorists.
