Not a concern-fag here either. But had a similar WTF scenario in our suburban neighborhood about a month ago. Had been doing some armature "baking" over on r/greatawakening re: CEMEX and some Hussien history. Next day an unfamiliar black suburban SUV was parked outside neighbors house with two agents in suits sitting inside watching our house. Husband noticed them when he pulled in and asked me to come take a look. I walked out and we began walking toward the vehicle. He said "hello" and asked if they needed anything. They just stared back. We got mail and walked back inside. Another vehicle then stopped next to them heading in opposite direction. They chatted and then both vehicles left. Have not seen them since. Should we be concerned?
