I don't sense a change in emphasis on drug crime vs. violent crime. However, since showing SWAT entries makes for good television, I think the "war on drugs" has gotten a lot more attention. Watch any of those "SWAT" tv shows that are coming on lately (I haven't yet). You'll see drug raids. You don't see or hear about raids on violent criminals by the SWAT/tactical teams because that's generally not how the violent guys are caught or dealt with. It's the drug dealers and the like who are sitting at home at 0430 who get the door knocked in. Violent criminals don't generally have snitches tipping the police to their whereabouts. THe violent guys get caught committing a crime or on some stupid minor traffic violation which subsequently shows the officer a warrant for their crimes.
First off, I don't really watch TV, so I cannot comment about various SWAT shows, and the like.
Second, the War on Drugs is more of a political tools then a legitimate way of combating drug use. The WoD puts more drug users in jail, every year, then violent criminals are jailed, leading to our overcrowded prisons. Adding to the political gains are the financial rewards to the PDs and various other LE agencies, via asset forfeiture laws, and what not.
However, the problem with the militarization of police raids is while they, the raids, are used against "violent criminals," they are also used against non-violent criminals and suspected criminals. With the inefficient system of informants, who are often self-serving, leading to false tips, more and more deaths and unneeded raids. Between 1985 and 2006, at least 40 civilians and 20 non-violent criminals were killed, and 22 LEOs were killed in often unneeded "Paramilitary Police Raids," according to the research done by Mr. Balko. These numbers, of course, leave out like "raids" performed by the BATF, FBI, and other Federal LF, notably the siege at Waco, the Ruby Ridge incident, etc.
While these tactical teams may have some use against fortified criminal redoubts and aggressive, criminal gangs, they have no purpose breaking into civilians homes at 4:30 in the morning, wearing all black clothing and masks, and terrorizing innocent men, women, and children, when the basis of the raid is a "tip" from a real criminal, looking to reduce his sentence.
