It is not credible to have a single person be omnipresent and can just hack any system with high encryption with ease. Especially with standard computers as shown in the computer teaching room. You would think all involved would have learned from the past break-ins so that he couldn't break in again.
Everybody knows what Pelant looks like, and he makes no attempt to disguise himself yet he is able to walk around without being noticed.
If the company would have been informed of what he looked like, it would have been simple for him to be denied entry. Just show the head of the company his picture and tell him to watch out for this guy, his plan would fall apart.
No matter what someone can attempt to change their identity, there are people involved, backups that aren't hackable and printouts. Any question would result in checks and he would not have been able to just walk out and go to a different country. He was fingerprinted and had a tracking bracelet on, you would think that those people who arrested and monitored him would have a say in his identity.
Some work of the FBI to storm into a building with guns drawn and not secure the surrounding area including the parking garage?
I hope that the story line that Hodgins is now broke doesn't continue because it would not be possible to just 'drain' bank accounts without records and ability to audit and recover the money.
Be assured that by just reading a file/picture/video that may contain a virus does not execute the code unless you have a stupidly designed system. Too many shows make this assumption that you can just insert a virus into any data and it will immediately infect a system.
