The motion detection uses motion sensors, which are only triggered by players. So it can't be the prisoners that were setting it off.
I would argue that this can't be completely true.
If you drop a box of explosives, it blows up regardless of how close it is to the player at impact. In the case of the explosives by the prisoners, what seems to happen is that the "prisoner" hits a box to the left and this causes the explosion. Moving slower does not help, you can just stand there and the prisoners will cause an explosion by their jumping eventually.
Perhaps the brain of the prisoners and the motion sensor for the bombs are connected?
