One would think an unarmed officer would at least be well trained in disarming techniques.
Even employing the best disarming techniques against someone wielding a knife and you are successful you can expect to be stabbed or slashed....Especially if the perp is knife combat trained....
Not enough. They do a weekend course every six months in unarmed arrest and restraint techniques. I’ve had over a decade of experience martial arts training (inclusing Ju Jitsu and Krav Maga) and even with that I am not confident that I could take on a knife wielding attacker and not end up getting stabbed or slashed 100% of the time. The average bobby does a hell of a lot less training than I’ve done and they’d be damn lucky if they managed to pull off a successful counter attack and disarm. They do in fairness have a baton and cs spray though.
