That doyene of Social and Judicial policy, Michael Winner, says so…
Film-maker Michael Winner, who is the chairman of the Police Memorial Trust, called for arming officers.
“The police are not equipped and I have put up memorials to 44 slain police officers.
“It is almost certain that at least 38 of those would be alive had they been armed and they would not have wives without a husband, children without a father or mother, [and] mothers without a son.”
