Was Shinwell reverting back to his old ways?

That was addressed on Elementary Season 5 Episode 18 when Sherlock and Joan grew concerned that their ally was a murderer when a drive-by shooting brought up a link to the past. 

Meanwhile, Holmes and Watson were reeled in to consult on a homicide "heard" by a new gunshot detection system. 

Was there an error with the system, or was there something more sinister going on?

Use the video above to watch Elementary online to get caught up with the latest developments for the characters.
