Umm... Amm.... Bizarre.... But making such incriminating evidence won't really help his case anymore...... O_o

That's why you got to be smart and clear your cache, history and anything else that can leave a trace, but depending on deep they want to dig they may be able to do some hard drive forensics and find the deleted cache from the hard drive. So overall, just take a sledge hammer to the hard drive instead.

well i guess like bitorrent sites thewy will have to shut google down now LOL. on top of that shut down G4TV.com too. That channels sucks

Even a sledge hammer might not be enough, some techs recovered data from a partially melted hard drive from the Columbia space shuttle. Your best bet is to either get a thermite grenade and set it off next to the HD, or to make thermite and set it off. Either way, your hard drive will be a pile of molten metal. When it cools, there will be no way to retrieve data.

Yeah but if its molten metal than they might be able to melt the metal and extract information. Your best bet would be to obtain a small yield thermonuclear device and set it off inside your computer. Just make sure you're no where near it when it goes off. Those pesky radiation burns can hurt you.

just format your hard drive seven or more times

You could also, you know, not kill your wife and daughter. Or kill other people in general. Or do massively illegal shit with your computer and then kill people. Or better yet, if you're considering killing, practice on yourself first.

Any of those would alleviate the need to dodge computer forensics experts. Easier than acquiring a nuke also.
