You guys seem to miss the point.

I can pick up a new laptop from walmart for $225.

Society changes a lot in 20, 40, 60, 80, a million years, but the government will STILL have your data.

Do you trust the government to never let your data slip out to someone else?

Do you trust the government to protect the integrity of the data over a long period of time and not let someone modify what was on your drive many years ago?

This is like letting the government just have your house to search through forever when they have a warrent, that is crazy.

If they want to search for contraband, they should do it with you there and no data shall copied off of your laptop. I would rather wait 4 hours for them to analyze my drive with me there and to know that I wouldn't have to worry about the data being used against my great grandchildren.
