Police have to dial back to days when flying squad was flying squad because they would respond to crime scene and kill the thugs.
This idea where police know a crime has happen - then zero in on the suspect a week or a month later - takes them to a forest - torture them - and then disappear them in rivers and or feed their bodies to hyena MUST stop.
Police should build 911 and trust for people to call them whenever a crime happen.
Quick response team armed with super bikes and fast cars should respond immediately - and finish the thugs - in public. Their bodies taken to morgue. Their relatives informed.
Nobody should be waylaid in middle of nowhere, tortured in a container, killed and dumped in some river.
Case of missing persons should cease...kill if you must...and do it publicly.
