if it was me i would try and place either fed agents or confidential informants inside to work there get all briefings watch everything, identify other workers for later..set up surveillance outside philly for sure all you need is to catch a few and they can lead to the whole plan. and probably detroit milwaukee..log all unusual actions, vehicles find out who the bosses are at each location etc..
historically the less people in on the conspiracy the harder it is to break..this looks like 5 states msm..etc..crack some eggs!
