Your lawyer can be a self dealing chiseler using knowledge you gave him or her, for their own benefit, going so far as to blackmail you and undermine you in the future.
Your lawyer is likely secretly taping your conversations and phone calls at any time, and may even be using correspondence you have with the lawyer for his/her own benefit.
Your lawyer could at anytime be working with a prosecutor to destroy you, and you would not necessarily know that is the case. In the links below I explain how that works in detail. To the thousands of people doing time, you need to reexamine in your mind how you may have actually been sent up.
Your lawyer may be a vindictive rat and lie about or embellish information given in trust to him or her.
Nothing you say to a lawyer is assured to remain privileged or confidential. You should assume as much.
Government agencies
like the Department of Justice and the
intelligence agencies can gain access to all of your communications
with your lawyers, in spite of an assurance of confidentiality, lawyer
client privilege and so on. In fact they will do so regardless of any
protections you think you might have. Information is a weapon.
The prosecution arm of government can use any illegal or even immoral activity your lawyer was involved in to leverage your lawyer to turn against you to save their own skin. That includes manipulating them to enhance and embellish the information to aid the government to destroy you. Conrad Black had this to say about it.
Complete and total hacks in government like Jerry Nadler,
using the flimsiest of excuses, can subpoena your information for their
own nefarious political purposes and your lawyer may be willing to
give it up.
