Actually, today was the first time I've seen any real collection since the last time I called the cops on them. They've come around in groups of 2 or 3, but don't stay longer than 5 minutes. Found out from LPD that someone had a pistol, 3 where tracked down and arrested, and 2 of those had outstanding warrants. They said a few had turned up at hospitals as well and are awaiting questioning. Also, I will probably be getting a court summons.
Also, there was a shooting a few blocks away last night, and someone got the snot kicked out of them earlier in the day about a block away. Didn't know about those until LPD told me. They've had a couple of unmarked cars driving by since it happened.
I ain't too worried. This actually tells me that I am probably not being specifically targeted, they have an apparent internal conflict that has them distracted, LE attention to this area has been increased, they are not well armed or organized, and their "optempo" (or whatever the gang equivalent is) has been disrupted.
