the point is that people who don't care go to lawyers to tell them how to move forward with appropriate caution. and privacy with a lawyers actual communication should be included. remember how lawyers (in movies tbh) often say 'let me talk, dont say anything at all', thats "maybe" because saying anything could reveal something the other party could use to win. if that doesnt include emails to be private, then why not directly use facebook or 4chan instead to tell the ither party how to win against your client? *lol

so if your lawyer doesnt take specific caution into account by himself what he would be supposed to tell you to do anyway, that lawyer is imo at best a risky bet.
