There is a shortage of IT law professionals. To be in IT law, your tech experience helps, but you also must have legal experience and qualified as a lawyer ( JD or equiv degrees).
The lawyers currently masquerading as IT Lawyers dont have real world IT experience , but however do know the law.
Well worth the switch in my mind, because:
1. IT Lawyers get paid more ( partly because there is less competition)
2. Some would argue it more interesting work
3. Higher growth potential.
4. More pay
5. Real world IT experience will put you in very good stead!!
This is a long term play, of course you need to go back to school and get law degree(s)-- easier said than done.
