Well, considering what they have to deal with, a SWAT team seems warranted in some cases. What happens in Vegas doesn't always stay in Vegas....or Mexico.Doesn't mean that they should have that. No agency should have that ability if they make regulations unless it is the legislature of a state or the country. Too much conflict of interest. Such enforcements personnel should be seperate as it can create bias.
Have you ever read the Monkey Wrench Gang by Edward Abbey? Abbey is a real hero here. He tried to prevent the government from taking the land, too. But they never attacked or threatened people...only property. Bundy's gang has threatened to hurt people.
