This would make surveillance laws socially much more acceptable. The politicians will claim:
- "We are surveilled anyway, so we can pass surveillance laws against citizens, too.", or
- "The citizens really ask for surveillance laws against specific groups (in this case: politicians). So, we will, of course, give the citizens what they want and pass surveillance laws against potential terrorists/child abusers/[whatever is currently fashionable]".
If you consider privacy or the right not to be surveilled to be important, this better should hold for the enemy (politicians).
