I don't know. They've gone back and forth too many times on this targeted thing.I agree, IMHO It would not take much skill to kill 4 college kids that were borderline functional from drinking in excess. There obviously was some sort of target as the LE has not cautioned people to be on the watch for a potential killer on the loose. If LE thought there was a major danger to the public they would caution people daily on being careful, setting alarms, staying in pairs and sleeping with one eye open. LE is obviously comfortable with the target scenario as they would otherwise be opening themsilves to all sorts of problems if heaven forbid another massacre occurs.
This perpetrator who killed four isn't in custody (rumors aside) - so my opinion is there is obviously is still a risk.
Kids are unfortunately used to living in fear now with the school shootings and whatnot, feeling safe is a thing of the past.
