while i'm not one to dismiss people suspecting themselves of being followed by agents of the state, you sound a little schizo. regardless, here are my thoughts on the matter. yes, it's possible this guy is a glowie. state agencies as well as federal love these fucking ugly obnoxious and gay suv's. chevy escalades, full tints, cadillac suv's, you name it. they love these fucking things. i've also noticed they're fans of minivans now too for whatever reason. if they're conducting a surveillance, they will use vehicles with plates that read back as "normal" tags usually. state dmv's will classify them a certain way so that the consumer doesn't notice anything "off" or wrong about them if/when they run the tags through a public database, but on the police side, they know or can tell that it's one of their own. having conducted surveillances before myself (never public sector, was briefly private), they won't use marked vehicles while conducting an investigation. sometimes in the case of the suv's with full tint, they will, because it's practically impossible to see inside the vehicle, it forces the subject or individual to go off of instinct or gut feelings. if you think you're being followed, i suggest looking into methods of catching a tail. there are a few publicly available and well known methods, but once used, they hardly ever work twice. no good deed goes unpunished op. i commend your compassion for vitcims of trafficking, but these motherfuckers are often complicit. don't bother wasting your time. there are countless instances of these retards laser focusing on the sources or people putting in the tips over investigating the actual claims themselves. that's why i almost never help police unless it's a matter or life or death circumstances for somebody or i see somebody being an insufferable douchebag.
