I think they should be able to do that as even in real life regular citizens have helped cops in some cases to block the road!
In the case above a civilian heavy equipment operator blocked the kill dozer and help to bring the situation to an end, he risked his life as the guy in the kill dozer had several guns!
This case is a bit diffrent as the cops commandeered a money transfering armored car to help them in rescuing wounded in a middle of a bank robbery.
Cops should get all the help they need logically
What you need to take into account is that these members of the public and non police emergency service personnel put their own lives at risk to do these actions because this is the real world and stopping injustice is the sworn duty of every citizen within their nation. Within PERP? Not so much as it ruins gameplay. These are also incredibly rare instances. Comparing a PERP shootout to the Killdozer incident is also a moot comparison, since this was a literal rampage where government infrastructure was targeted, resulting in this last resort measure. The closest thing to a killdozer rampage you have on PERP is roadcrew workers and firemen evading cops in their heavy vehicles which can be quickly thwarted with a few shots from an M16 anyways.
In the case of the North Hollywood shootout, well, that’s why armoured trucks are now in police service regularly, including within PERP. The police are no longer required to commandeer non government issued vehicles.
This is entirely disallowed.
What if a police man told them to block the road with their vehicle? If they didn't comply with that order then they would be breaking the law!!!!!!
You have a right to disobey police orders if they go against the duty of care policy in a manner which would put you at severe risk of harm. You are also required to, by rules, not enter a crime scene that is not secure, thus giving you more ground to not comply with unlawful orders.
And talking about realism, then bank robberies shouldn't be happening in the middle of the night? With 6 crims and 3 cops, robbers leaving bank to kill everyone they see in the whole city on the bank side just because.
I mean, there’s still money inside the bank 24/7. The method of bank robbery portrayed on perp doesn’t require you to interact with any employees and either way the bank is walled with glass with 3 doors so there’s plenty of ways getting in even when the roof is completely disregarded.
Back onto the original topic:
What you have to remember that just like in reality, crime on PERP is oriented around not getting caught. Killing cops is reserved only when you or your party have already killed someone. Upon killing cops, realistically there’s no crime any higher you could possibly commit, in the USA, killing a police officer in the line of duty will almost always guarantee a death penalty in states which still carry capital punishment out on unrehabilitatable offenders.
Once you’ve killed a cop the bar cant really go any higher so logically theres no reason beyond personal morals to not kill an ambulance driver or firefighter who attempts to get you killed or apprehended by law enforcement to ensure you never step foot outside of a prison again except in a body bag. It’s also worth noting that the Moral code of a cop killing armed robber who killed police in defence of some stolen drugs and guns isn’t necessarily that high if they’ve valued a few batches of drugs and guns all collectively valued probably no more than the cost of a Vauxhall Corsa over human lives, including lives of those who dedicated and eventually gave their whole lives away to stop these crimes happening.
Tl;dr: You are within your right to defend your life and freedom from a violent felony sentence and anyone who stands in your way for whatever reason is an aggressor and should be shot down. Furthermore, Putting yourself in this situation as an unarmed / inadequately armed government employee who doesn’t specialise in any sort of law enforcement should not put themselves in situations which have any sort of chance of resulting in them being shot and killed. Apprehending suspects as a non-armoured, Non-firearm wielding government employee is 3.4, this includes even things like cars fleeing from traffic stops and the likes because you don’t know the limit of what that person is willing to do to not get arrested.
