Ask HN: Need help from police officers for problem validation

we are a group of software architects working on a solution for public safety domain, primarily for police officers. Are there any police officers here on HN who are willing to provide us their valuable feedback? Preferably a short call (not more than 15-20 min). We just wanted to make sure that the problem we are trying to solve is a valid concern before we go ahead and start spending more time on it. Thanks in advance!
