A relative of mine was arrested with 9 charges of terror threats and harassment with 10 more to come. The detectives traced the IP to his business. He simply said I sat in his parking lot and did it with a laptop...thats why the IP LOOKS like it came from his business. The detectives werent worried about his response but I am that he may wiggle out of it. They did NOT take his hardrive. Can someone help me with knowledge? The things in question are fake citysearch profiles and facebook. Each requires an email to register.
We're not attorneys so it's probably best to seek legal advice since those are pretty serious charges. I'm sure at some point computer forensics will be brought in to the picture. At which time, they'll be able to discover the source.
In the meantime, don't do anything shady on your computer to raise flags if you're not guilty. In other words, don't format it, don't install file deletion software, etc.
