DNS, I entirely agree with your analysis.
- There's a fair chance the work won't be completed.
- If it is, the results aren't likely to show any effect on crime.
- And to go back to Gary's point, if someone uses even one of these guns in a harmful way, that's what will get the publicity.
So, yeah -- I'd say this is mostly a publicity stunt, with a pretty small chance of a good outcome for us.
