“We never received any sort of rational explanation, apology or compensation for the damage they caused.”
That’s what they were hoping would happen. You missed the boat by not suing them at the time of the incident. The only way this stuff stops is when it gets enough attention, and it costs government large sums of money!
I disagree. Our legal system is now so completely screwed up that everything that it touches gets distorted and the results have little if any positive benefit. In general the only persons who benefit from the legal system are lawyers and politicians. Suing the SWAT team would probably have turned into a huge hassle; it might have got us a little compensation but no positive changes would likely have been made.
Government money = your money, your family's money, your neighbors' money. It has to cost the government workers involved personally or it will continue apace.
