Legal Question in Criminal Law in California

It is very legal. If they dig long and hard enough, they may even charge you with a felony. Now is the time for you to get an attorney.

Perfectly legal. And, they can change again at any time the prosecutor feels he can justify them.

Of course you can fight the charges. When arrested or charged with any crime, the proper questions are, can any evidence obtained in a search or confession be used against you, and can you be convicted, and what can you do? Effective plea-bargaining, using those defenses, could possibly keep you out of jail, or at least dramatically reduce it. Not exactly a do it yourself project in court for someone who does not know how to effectively represent himself against a professional prosecutor intending to convict and jail you. If you don't know how to do these things effectively, then hire an attorney that does, who will try to get a dismissal, diversion, reduction or other decent outcome through plea bargain, or take it to trial if appropriate. If serious about hiring counsel to help you in this, and if this is in SoCal courts, feel free to contact me.
