Here's how the department spokesman described Group Violent Intervention They say Group because they're not allowed by Fischer to say Gang.: "We review each incident involving fatal and non-fatal shooting from the prior week and from those we identify the individuals who have a high probability of retaliation and we right there go talk to them" In other words, they try to figure out which gang a victim belonged to, then go talk to the gang's shot-caller like they're Robert Duval in the movie "Colors".
