Prosecutors in the US plan to start deleting data from the servers of file-sharing site Megauploads this week.

Uh huh, sure ;).

The move has lead to claims that wiping files could make it impossible for the accused to defend themselves and deprive millions of users access to their personal files.

This doesn't pass the smell test for me. I fear that access to data will be revoked, but law enforcement will maintain it to mine at a later date. On hard drives without encryption that people leave in taxis by mistake, but that's another issue.
