I think not John. I rather suspect that NYPD's interpretation of shoot to stop is slightly different to that of the Met. I'm sure an NYPD officer doesn't have to consider the health and safety implications within a 3 mile radius before he shoots a scumbag.
I rather suspect that if NYPD had turned up to Woolwich in the aftermath of that awful incident we wouldn't be putting the scumbags up in prison whilst awaiting their no doubt expensive trial .
