Authorities in Mississippi are warning drivers about a possible fake police officer who may be pulling drivers over and then shooting them dead.

Two drivers were found shot and killed in two separate incidents in northern Mississippi last week, CNN reports. "The concern is that someone is posing as a law enforcement officer, and that is how these vehicles end up on the side of the road," the director of the Mississippi Bureau of Investigation said Monday.

The MBI is warning drivers to be wary if an officer attempts to pull them over, and suggests two courses of action if a driver is suspicious about a traffic stop Mississippi:

It's never a good idea to drive drunk -- it puts people's lives in danger. But just because you did something wrong, doesn't mean you should give up your right to refuse a breathalyzer test, right?

Not exactly.

So let's get down to it: Are you legally allowed to refuse to take a breathalyzer?

While you might be hoping that the answer is "it depends on your state," it's actually the opposite.

A man who was pardoned by former Mississippi Governor Haley Barbour has been charged with driving under the influence. The man was convicted for DUI three times before, Reuters reports.

Harry Bostick is accused of crashing a car into another vehicle while driving drunk. The collision killed the other driver, 18-year-old Charity Smith. Bostick, a former IRS agent, allegedly left the scene following the accident.

Bostick received one of the over 200 pardons from ex-Governor Barbour earlier this year. He was given the pardon for a 2009 felony DUI conviction. So why was a thrice convicted drunk driver allowed to go free?

A "sensitive" law-enforcement device aimed at stopping terrorists led police to pull over a radioactive man who'd just undergone a medical procedure.

A Connecticut state trooper conducted the traffic stop after a passing car set off a radiation detector in the officer's cruiser, the Connecticut Post reports. But instead of finding hazardous materials, the officer found a perplexed off-duty firefighter.

"I asked the officer, 'What seems to be the problem?'" firefighter Mike Apatow told the Post. "He said, 'You've been flagged as a radioactive car.'"

Would you want your mom to help you sext? Probably not. And even if you did, it's doubtful that your mom would even give you sexting help, right? Right. Which is why this story is so disturbing.

A 35-year-old Utah woman has been arrested for helping her 13-year-old daughter take nude photos with her cell phone. She allegedly did this knowing that the photos were to be sent to her daughter's older boyfriend.

That boyfriend is 30-years-old and lives in Oregon.

Another "tanning mom" is facing child endangerment charges, but not for allegedly taking a child into a tanning booth.

Police in Elizabethtown, Pa., arrested Krista Mann after finding her two children -- a 6-year-old girl and a 10-month-old boy -- unattended in a running car while she went tanning at a salon across the street, WGAL-TV reports.

An officer approached the car and asked the girl where her parents were. The girl told the officer about her mom's tanning appointment -- but then said she wasn't supposed to talk to strangers and started to cry, police said.

Ex-FAA Chief Randy Babbitt is now cleared for departure, after a judge dismissed an embarrassing DWI charge that led to his ouster from the agency.

Babbitt, 65, resigned his post in December after he was arrested for an alleged wrong-way DWI in Virginia. Babbitt underwent an alcohol breath test at the scene, but police initially declined to publicly release the results of that test.

Now we know why, thanks to evidence that Babbitt's DWI lawyer introduced at trial -- including video of Babbitt's arrest, which convinced the judge to toss his DWI charge, the Associated Press reports.

Despite claims otherwise, Joran van der Sloot's extradition to the U.S. is not yet set in stone. Though a Peruvian judge approved his "provisional detention" last month, the convicted murderer has indicated that he intends to fight his extradition.

In court on Tuesday, van der Sloot told a judge that he would rather serve out the remainder of his 28-year murder sentence in Peru than be sent to the U.S. Rumor has it his jailed lifestyle is significantly more cushy than it would be in a federal prison.

What is an arraignment? It's a crucial step in any criminal case. Life can present all kinds of surprises. And even the most upstanding citizens can falter every once in a while.

An arraignment is the first courtroom proceeding defendants will encounter. Are you itching to find out what an arraignment entitles? You're in luck.

America's first 911 texting service is a potential life-saver, and the FCC is calling for even more future 911 upgrades such as photo and video messaging.

Verizon Wireless is set to be the first U.S. carrier to offer a 911 texting service, which will allow customers to send cell-phone text messages to a 911 dispatch center, PC Magazine reports.

The result could be potentially life-saving, especially for hearing-impaired customers who are increasingly turning to text messaging. It could also come in handy when time is of the essence -- or when it's too dangerous to make a 911 phone call.
