In the few worse cases, it will mean some lost time, because the first responder cops will have to wait for assault teams. But in the 95% cases were a SWAT team wasn't need, it prevents unnecessarily violence escalation. And there are many more lives saved by non-escalation than lives lost to intervention delays.
Also, SWAT teams are considered elite forces (almost?) everywhere; but in some countries, elitism is based on sharpshooting abilities, in some others it's based on good judgement, clear-headedness and restrain.
One reason swatting is not done so much in Europe
Swatting is the act of making the prank call. It has nothing to do with how the SWAT team handles it. Nowhere have I argued that European police wouldn't have handled it better. That is a completely separate question from the question of how often these calls get made and why.
That's pretty anti-climatic, as a prank, and that's why nobody will bother making it.
General police violence in the US is not a justification for saying the caller should not be held responsible for their part in this.
I don't see people saying he should not be punished. They say that cops needs to change.
Focusing on his punishment is like adding yet another hack into badly engineered system - it makes people feel good and makes one bug go away, but it does nothing to address root cause which is bad system.
Me asserting that it isn't okay to let him off the hook is not the same as me saying the system as a whole is fine and does not need reform.
Arguing with me from that angle amounts to putting words in my mouth.
And somehow in your mind this makes the caller less guilty of the death that results.
