Could Use Some Advice...

Errors of process, procedure, or mistakes of fact can lead to a mistrial or can be possibly used to your favor. If an error prejudices a jury against you, or violates some right you have as you go through this process, it could be used to your favor. A typo on an enevelope cannot unless (for example) you are trying to argue it is someone else and they have you confused with the persons whose name is on the envelope........ There is not much benefit in this circumstance of a typo on a letter.

You are right to some degree (although a bit harsh) in your assessment of how the legal system works----it is how law and order are kept, in part, by a vigorous pursuit of lawlessness for which, for the most part, law abiding citizens are safe. That doesn't mean that at times, it never breaks down nor is it perfect. The law however, is fair in that it provides you with the guide you need to navigate, the public defender whose services are taxpayer funded.

Good luck. +
