On the F.B.I. Citing Security Concerns as its Main Rationale for Turning Off the Security Cameras at Mar-a-Lago During Their Gestapo-Infused Raid of the Place

  It's totally nonsensical and so we either have a bunch of nimrods who know squat about security (there generally aren't enough agents to man every point of entry and so the security cameras and consoles make it so that one agent can observe multiple points of entry at once - maybe they didn't know that, which itself is frightening) or a large contingent of people who are trying to hide something (staging photos, for example). My suspicion is that it's probably both with the latter being the bigger contributor.
