As President Donald Trump ordered a ban on gun modifications Tuesday afternoon, Denver police saw zero engagement with their plan to get the locally illegal bump stocks off the streets. On Friday, Denver police announced the public could turn in bump stocks to the department in light of a recent change to the municipal code making the gun modification illegal in response to the October shooting massacre in Las Vegas. With the recent national and local spotlight on gun control, Denver police said they received several inquiries wondering how their roll-out of the turn-in has gone so far. “Since Friday…zero devices have been turned in to the department,” Denver Police spokesman Doug Schepman said in an email.
