High-Tech Gunshot Detection System Fails

Expensive microphone system missed gunfights

A £150,000 'bullet beater' system that was introduced to crackdown on inner city gun gangs has failed to detect four confirmed shootings in the last 12 months.

Details of the Shotspotter system's failings were revealed on Thursday by police chiefs who told a Birmingham community meeting that it will cost at least £40,000 per year to monitor the system in the future.
