"But I'm Innocent!"

Lying on his family room floor with assault weapons trained on him, shouts of "pedophile!" and "pornographer!" stinging like his fresh cuts and bruises, the Buffalo homeowner didn't need long to figure out the reason for the early morning wake-up call from a swarm of federal agents.

That new wireless router. He'd gotten fed up trying to set a password. Someone must have used his Internet connection, he thought.
"We know who you are! You downloaded thousands of images at 11:30 last night," the man's lawyer, Barry Covert, recounted the agents saying. They referred to a screen name, "Doldrum."
"No, I didn't," he insisted. "Somebody else could have but I didn't do anything like that."
"You're a creep ... just admit it," they said.
Law enforcement officials say the case is a cautionary tale. Their advice: Password-protect your wireless router.
Plenty of others would agree. The Sarasota, Fla. man, for example, who got a similar visit from the FBI last year after someone on a boat docked in a marina outside his building used a potato chip can as an antenna to boost his wireless signal and download an astounding 10 million images of child porn, or the North Syracuse, N.Y., man who in December 2009 opened his door to police who'd been following an electronic trail of illegal videos and images. The man's neighbor pleaded guilty April 12.
For two hours that March morning in Buffalo, agents tapped away at the homeowner's desktop computer, eventually taking it with them, along with his and his wife's iPads and iPhones.
Within three days, investigators determined the homeowner had been telling the truth: If someone was downloading child pornography through his wireless signal, it wasn't him. About a week later, agents arrested a 25-year-old neighbor and charged him with distribution of child pornography. The case is pending in federal court.
It's unknown how often unsecured routers have brought legal trouble for subscribers. Besides the criminal investigations, the Internet is full of anecdotal accounts of people who've had to fight accusations of illegally downloading music or movies.
Whether you're guilty or not, "you look like the suspect," said Orin Kerr, a professor at George Washington University Law School, who said that's just one of many reasons to secure home routers.

In this article they make it sound like having an unsecured router is the issue here.  But I know people who know, and they say if someone knows what their doing, you password means nothing.  They describe it as "laughably easy".  That being said, I always say, "better to make them work for it."  It's kind of like the idea of a bank vault.  Obviously for a "professional" bank robber a vault is little deterrent, but for everyone else it works just fine.

So while a hacker with skills may be able to crack my password, I'm betting that guy is busy hacking things worth hacking.  But my broke neighbor who can't afford internet service?  He's not walking into my network scott-free.  Nope. Not happening.

I wonder how many times something like this, where folks who were innocent are getting jammed up, happens on average?
