They have weapons attached? Seems like the people that attacked us last time did not worry about their pictures being taken.... They even died performing the deed. What kind of deterrent is a camera for a person willing to die?
Don't worry - troops can be sent from the fort. :)

They would be detected and folks with weapons would be there pretty quickly, I would guess / hope that is the plan. The bridge has independent management from M-DOT, and every issue concerning the bridge is handled by folks who have nothing else to tend to.
The camera itself is not a deterrent, it is a tool to allow us to get to them before the deed, so that their death is in a time and manner of OUR choosing, not theirs.
Prayers up!
