Can they really not catch the morons shooting automatic weapons?

Semi and automatic shots heard from Blackwell over a period of 10-15 minutes and if I had to guess it's being done around Belle Isle based on the direction of the sound. Not the first time I've heard this. They literally have two ways to get off the island. Put these tools in jail, please. I presume it's much closer to those near the river. I'd call 911 but I wouldn't be able to give them anything specific besides general direction. Anyone else hear it?
