I like to think that as opposed to simple citizens, lawyers, who are officers of the court (yes?) are in HUGE trouble if they present false evidence.
Liberty for the accused is at stake.
Lawyers who present false citations should, at a minimum, be disbarred.
Disbar a few and the rest will get the message that they should research their citations.
The thing is that lawyers who do this always get caught, and there have been stories about it for 2 years or so, but some still make that mistake. The other side will recognize they are fake cases.
