No, it's definitely not. Any lawyer who lies can be disbarred. It's something that every lawyer learns to not do first day of law school... that said, you also learn lots of ways of not saying anything, but implying quite a bit... e.g., you wouldn't say "we found the weapon" when you really didn't, but you could say "we're gonna get the weapon".
