As much as I dislike these dudes for their actions, instead of throwing them in prison I would consider hiring them, if I could afford the money to keep'em loyal.
This is not very smart. Come on, you know this is not smart!
In the early days, this may have been done once or twice. But today, no business does this anymore; especially not any company in the business of life-critical security such as the electric grid providers, the oil and nuclear fuel industries, airlines, aerospace and defense companies, medical equipment makers or service providers, or the banking system.
You just can't do that! First off, 96% of all crimes are commited by somebody who has already committed other crimes!
A court would see this, so if you hire somebody with a dirty record and they then commit another crime at your company, YOU as the hiring manager could be up for a long jail sentence yourself. Or you could be open to civil lawsuits from your co-workers, shareholders, customers, etc. If your hiring decision was made in spite of knowing that something bad could have been prevented, then you could even be open to personal lawsuits.
And good luck trying to get a jury to believe your claims that you "didn't know this could happen!"
You'd be lucky if you only got fired for being an idiot and hiring somebody with such a record who then went on to commit new crimes while in your employ. Getting fired for such foolishness would be the LEAST you could expect to happen to you.
Furthermore, you also can't just give a security clearance to a convicted felon; the feds will reject that application all day long. And many companies require a valid security clearance as a condition of employment, particularly with sensitive government contracts.
Sure, they are "thieves", but highly knowledgeable. They have broken into stuff that should be a lot better protected. The pipeline should never, ever have been so "easy" to get to, that is just scary! What other critical infrastructure has sh*t security?
This is why bug bounty programs need to really pay off, Apple! Make these a**holes work _for_ you, not against you.
And the rest is just as silly and just as dangerous. You need to rethink your position before you become a business owner or hiring manager.
