The Finnish police are naturally carefully instructed and trained on how the warning shot has to be performed to eliminate any immediate danger to anyone. I have to add that I should've clarified this the first time I mentioned it, I just wrote "a warning shot in the air", which is misleading in all kinds of ways. Sorry for that.
The problem is, there is no completely safe way to fire a warning shot. Period. A shot into the ground or solid background always has the risk of a ricochet. A shot into a building has the risk of ricochet or penetration, depending on the type of building material. A shot up into the air is going to come down somewhere, with enough energy to penetrate a skull.
That is why the majority of police in the US are trained that they do not fire their weapon unless there is a clear and present danger, and the only way to eliminate the danger is to shoot the suspect. In that situation, you don't have time to be messing around with multiple warnings (which are typically given long before that point), or warning shots. You shoot to end the danger in the most effective way possible.
There is no completely safe way to fire on a suspect, either; but in that case the benefit outweighs the risk (and cops are trained to minimize risk). Definitely not the case with warning shots. The risk is still rather low in most circumstances; but the utility is effectively zero.
He watched the vid and commented on the lack of info, but also said that generally the Finnish police would not ever approach the suspect in this way, but understands that in other countries it might be necessary. He also said that, regarding their instructions, the current model works very well in the streets. I was a bit surprised in hearing that, he didn't feel that the regulations limit their work in any dangerous way. I guess I must've been uninformed / exaggerating when I mentioned about incidents popping in the news. Of course he had many stories to tell and examples to give, but in general, stuff like this is VERY rare in Finland.
I'm guessing that Finland has a negligible gang problem. What are Finland's drug laws like? The majority of the time that a police officer in the US is required to shoot a suspect, the incident is gang-related, and gangs exist in their current form primarily due to the huge back-market drug trade profits.
People castigate the US for it's violence, and act as if all Americans are psychotic murderers waiting to happen as soon as they get their hands on a firearm; but that's a grossly unfair stereotype. The vast majority of the violent crime in the US is gang-related, usually extended disputes over drug distribution territory. Much the same way that alcohol prohibition financed the rise of organized crime in the '20s.
Because of the drug money, gangs have been a much bigger problem in the US than they have in most of the rest of the developed world. This has been mainly due to the fact that we're one of the most prosperous nations, therefore we have far more money to spend on drugs; as well as having some of the most restrictive drug laws in the developed world, which encourages the growth of the underground economy and criminal enterprises. Although from my reading, the UK is beginning to see a significant increase in violent gang activity as well.
