Most patrol cops have zero training in mechanical breaching, so your experience isn't necessarily relevant here in establishing the potential actions of a "reasonable officer".
I've had a decent amount of training from multiple sources (to include firemen) but don't do it everyday, and I wouldn't make the claim as you. There's a reason that SWAT teams usually have a dedicate breacher who can specialize in that role to maintain proficiency, and there's a reason that firefighters are a common source of instruction for cops looking to learn or improve breaching...I seriously meant what I said earlier that you guys are artists about it, and it's unreasonable to expect a random LEO, especially a patrol cop, to replicate your capability.
