Police Activity in Town Madison

Technically Madison not Huntsville, but did anyone else see or know what was going on in Town Madison last night (4/3)? Saw at least 3 black Madison PD squad cars pull up between Ballpark and Palmer House Apartments at around 11 pm last night. Then witnessed at least 5-6 officers walking around on foot, then 3 white Huntsville PD squad cars drove past a bit later. Was there a joint training exercise or man-hunt going on or something?
