From a law enforcement perspective, I guess I can see how so-called vigilante justice could be considered problematic. But as a parent, the idea of a group of moms and dads/amateur sleuths posing online as underage girls and starting web chats with pedophiles in the hopes of catching them in their own trap? A group whose efforts have already led to the arrest of seven suspects?! I see no problem at all!

Think To Catch a Predator, except instead of Chris Hansen busting the alleged pedophiles, there's a bunch of pissed-off parents with a video camera. Which is scarier?

I'd say the parents, who go by the name Letzgo Hunting. As the organization's leader -- known only as Scumm Buster -- explains, "We want to protect children, we are parents ourselves and a couple of us have got children who are in their teens -- the same age as the girls we pretend to be."

I am not a fan of the NRA. I am not a fan of guns. If you asked me whether or not I'd want a kid wearing a T-shirt that said "NRA" with a picture of a gun on it to the school where my children also go, I'd say "No." But then I have to ask myself why -- beyond my personal opinion of the NRA. And that is where I get stuck. An eighth grader in West Virginia was arrested after refusing to take off his T-shirt, which had the NRA name on it and the motto "Protect your right." The school's clothing policy doesn't specifically ban a shirt like that, although it comes close, as it bans clothes that "display violence."

Google Maps and Google Street View have been known to capture all sorts of oddball images, but evidence of a spectacularly grisly murder was a first. A Reddit user recently called attention to an image taken by an aerial Google Maps camera in the Netherlands, which shows what appeared to be the dramatic scene of a crime. In the shot, a shadowy figure seems to be dragging a corpse down a pier and over the edge, leaving a gruesome smear of blood behind the body. You can barely make out the shape of a human body, with the "head" on the right and the "feet" on the left. A body-shaped smudge to the right implies that the corpse left a large bloodstain before someone flipped it over.

Horrible, right? The image was captured in 2009, but Dutch cops could still prosecute if they found any remaining evidence, since there's no statute of limitations for murder. While the debate raged on over what, exactly, the photo depicted -- one Dutch citizen came forward and confessed.

Sometimes it's quite easy to dismiss the world of professional sports as nothing but psychotic, aggressive, delusional fans cheering on spoiled, multimillionaire athletes who lack any kind of class or moral compass -- but you have to admit, at the same time, sports can unite and inspire us unlike anything else. Just take a look at what happened during the National Anthem at the Boston Bruins vs. Buffalo Sabers game last night, the first professional sports event Boston hosted since the devastating and tragic Boston Marathon bombings.

Blue and yellow ribbons were projected onto the ice at TD Garden before the game while Rene Rancourt appeared and began singing the National Anthem. Fans in attendance started singing along, and eventually their voices took over to the point that Rancourt deemed it appropriate to lower his microphone. What happened next is something you won't soon forget.

Seems like more and more people are totally misunderstanding what 911 is meant for -- true emergencies. Not for a divorce or because you're annoyed with your mother. And yet, the latter is disturbingly the reason a 19-year-old in Vero Beach, Flori-duh named Vincent Valvo called 911 recently. He actually called twice to complain that he "didn't like how his mom was talking to him." OMG. And we thought the divorce one was the height of craaaazy!

Thank goodness the police refused to take this one lightly. They showed up outside his home at 4:30 a.m. and arrested him for "abuse of 911." Faaaantastic.

The second fatality in the Boston Marathon terrorist attack has been identified. She reportedly is Krystle M. Campbell, a 29-year-old restaurant manager. The beautiful freckle-faced blonde was at the marathon with her friend, Karen Rand, watching Karen's boyfriend run the race. Both were hit with the explosions, and what happened next is truly something out of a horror movie. Both women were rushed to the emergency room, and doctors mixed up their identities. That resulted in Krystle's parents thinking that she was alive and being operated on. They only leaned the truth when doctors escorted them into the operating room to show them their "daughter."

They sound like skits on Saturday Night Live, but B*tch, Don't Steal My Prom Dress! and/or Steal My Prom Dress and I'll Knock You the F**k Out! are just two of the names commonly used for online prom-dress groups where girls can post pics of their newly purchased gowns as a warning to anyone attending the same dance: Wear the same dress and suffer the consequences.

Honestly (probably because, as mentioned, they reminded me of something you'd see on SNL), my first reaction to these, um, aggressively-named groups was to laugh. I mean, the kids behind these forums and web pages can't actually be taking them seriously ... can they? Surely the titles are tongue-in-cheek.

Horrible news broke today that two bombs were detonated near the finish line at the Boston Marathon. So far, it's been reported that at least two people are dead and at least 23 are injured. Social media immediately became a lifeline for people trying to find out the status of friends and family. The Boston Marathon sent out messages on both Facebook and Twitter telling people to meet at the Boston Common in order to check in. Within hours, a website run by the Red Cross went up where people can list themselves as safe or look for runners and Google launched a person finder.
