Check out 2:45 on this video - US riot police showing how intimidating the shield bash. It's the first time I've seen footage of police doing this:

I've never seen them form interlocking shieldwalls either, I think generally their shields are too small and they don't need to because they're generally not actually under attack. Anyone know if this occurs in modern day shieldwalls at all?
Different force, but I know the MET don't pull their blows :(. Maybe I could train them to be pacifist combatants? Dunno how long they'd have held Senlac hill with <s>hippies</s> domestic extremists like us holding it:
