Well Good grief! If I saw armed men running at my house, I'd be screaming too!! These guys are idiots!
The problem is the tactical nature of the "raids".
There is no way in a democratic society we should have police forces behaving like this.
The problem seems to have started in LA in the late '70s or early '80s. Gang bangers had crack houses that were essentially fortresses. The cops would show up, bang on the door. The gang bangers wouldn't answer, the cops would kick the door and since it was about two inches or reinforced steel nothing would happen. Bottom line is it would take about 10 minutes for the cops to get into the crack house, by which time all of the evidence would go down the cloaca. No arrests would be made, liberal judges and the press would question the probable cause for the warrant and everybody except the drug dealers would go away unhappy.
The chief Gates of the LAPD said screw it and went out and got himself an armored car and had a 20 foot battering ram mounted on the front. This solved the entry problem but it had some limitations. First, you needed a good run at the door with the ram, second, it was expensive and third, it was a bit conspicuous - drug dealers tended to see it coming.
The ultimate solution seems to have been the "tactical raid". Lots of well armed cops with hand held battering rams would show up at odd hours and just start yelling and smashing in the door. This generally got the cops in the door before the drugs where all flushed and it made for great TV.
The problem is, it relies heavily on the element of surprise which has lead to several tragedies over the years.
The only solution I can see is for law enforcement to change the way they deal with barricade situations.
The courts need to loosen up on probable cause. If police serve a search warrant and no contraband is found, too bad they flushed it. No expensive trial, no expensive incarceration and the perps are out the cost of the drugs.
Agencies should place more emphasis on buy/bust operations and less on forced entry.
Agencies need to remove the emphasis on the big, photogenic, drug bust. If you catch a dealer with a marketable quantity of drugs it should not make any difference if it's ten grams or 200 kilos. Courts should treat them the same and put the perps away for a long time.
Eliminate "no knock" warrants in cases where someone's life is not suspected to be in immediate danger. Implement a 60 second rule, allowing the home owner a full minute to secure their pets and get to the door before they break it down. If the perps flush the drugs, good, let them. It cuts into their margins.
One word about dogs; I love dogs and I agree that what happened in this case was tragic and unnecessary. But if I were a cop and some drug dealer's pit bull was coming at me that sucker would be real dead real fast.
