Calling TIPS will work. It just takes time. If you call and a CO is in the vicinity, he/she can act. Does not work if the CO is the other side of the county.
TIPS is not 911 dispatch. It is an info source similar in some regards to Crimestoppers. The more calls placed to TIPS, the more attention will be paid to your specific area. It does not happen overnight. Repeat complaints have brought about enforcement blitzes in problematic areas, but requires drawing in extra manpower resources. I've seen 30-40 people get tagged in a single blitz. It happened because numerous repeat calls to TIPS helped them identify a problem area.
In Niagara we have 3 CO's covering the region 24/7. 2 years ago we had 2 until they realized, from call volume, that resources were inadequate. Still not enough but an improvement.
