Saw this in another forum. I think it's being sensationalised a little bit. Apparently he selectively deleted particular days of the week, rather than just 'remove anything in the cache'.
I've had my browsers set up to clear cache at closing for years now -- it seems like intent is key for being able to charge someone with this.
The penalties are quite different if you're just throwing out what you perceive to be garbage and "ooopss.... the murder weapon was in that trash can" versus willfully destroying evidence.
I am an ardent critic of the burgeoning police state in the US post-9/11, but headline and slant of this story is just kind of stupid.
It would be like the IRS investigating the banks and prosecuting them for shredding evidence and the headline reads "Banker threatened with 20 years in prison for taking out the trash."
