A county sheriff in Washington state is warning smash-and-grab thieves that the "tactics have changed" in how deputies will respond to the burglaries, allowing for authorities to be "relentless" in their efforts to capture them under a new interpretation of the law.

Thurston County Sheriff Derek Sanders posted a short video to Facebook on Tuesday, telling would-be smash-and-grabbers to "get a better plan," because their current plan "is no longer going to work."

"If you come to Thurston County, and you decide you're gonna do tens of thousands of dollars to one of our businesses in damage, you're gonna smash that stolen car, and you're gonna hop in your buddy's stolen car and flee from the scene; we're now going to chase you," Sanders said. "We're not pulling over, and the state's law is no longer going to protect you." 

Authorities are not allowed to pursue suspects in burglaries under current state law, which considers the crime a second-degree offense, according to Sanders.

But following a spate of smash-and-grab robberies involving stolen vehicles, the sheriff said that Thurston County officials are now interpreting crimes that use vehicles to cause damage as burglary with a deadly weapon, a first-degree offense that will allow authorities to pursue the suspects.

"If you flee, we'll chase you, we'll conduct a pit maneuver, and we'll use a tactical vehicle intervention to pin your car in," Sanders said. "If you flee on foot, we'll chase you on foot then, too. If we lose you in the foot chase, then we'll send the dog after you."

The sheriff added: "We are going to be relentless in our efforts to capture you."

The warning comes after multiple small businesses were targeted in recent months by suspects using stolen cars to crash through storefronts in what Sanders called a growing crime trend.

Businesses that have been hit include marijuana shops, a pipe store, gun shops and boutique stores.

"They are driving small business out of our area, and as a community we cannot and should not tolerate it," Sanders said.
