National Museum of Crime & Punishment

"Great museum, well worth the Groupon!"

"Both sides of the law are explored in depth through a fascinating history of crime dating as far back as the medieval era. Join pirates, outlaws, bank robbers and the lawmen who captured them."

"I was really happy to see an exhibit on dog fighting. I would have liked to see more people stop and educate themselves instead of pass right through that section. Dog fighting is a crime."

"In the nation's capital lies a plaster death mask cast from the corpse of one of America's most-wanted gangsters, John Dillinger. But is it really his face, or does the mask prove he got away?"

"Try the FBI shooting game- awesome."

"Great trip for teachers. Teachers get free admission with students."

"Definitely kind of creepy...but I guess you can expect that."

"On April 1 1845, Samuel Morse opened the world's first telegraph office on this location. Messages were sent in a coded alphabet consisting of electronic dots & dashes which became known as Morse Code"

"This is one of the few museums you have to pay for in DC, but it seems like fun. We visited the gift shop, not the museum and they had some fun presents you could buy as souvenirs."

"The museum has great artifacts and is organized by era. Don't leave without trying the FBI shooting game."

"Give yourself at least a couple hours here, there's a ton to see and read. Definitely worth the admission ticket."

"Got half off for checking in on Foursquare!"

"Not worth the $22 admission price"

"This is a terrible museum. Nearly every sign contains grammatical, spelling, or factual errors. The amount of mistakes are inexcusable. Don't waste your money."

"To charge you USD 21 for this... It's a perfect CRIME!"

"$6 tickets for MD VA DC residents on Sundays."

"Awesome museum! Chronologically structured, easy to navigate, interactive. John Walsh films America's Most Wanted here every Saturday night at 9pm...$25 per ticket."
