Firearms and Weapons

There are various laws regarding firearms and other types of weapons.  These laws can be so complicated and specific that often even law enforcement is not fully aware of the nuances.  Weapons violations can be misdemeanors, felonies, or wobblers (chargeable as either a misdemeanor or felony).  Conviction for some violations can result in a 10 year or even lifetime ban from owning a firearm; a conviction for others has no impact on your right to have a gun.  If you commit a crime while armed with a deadly weapon or a firearm, the increase in possible sentence can be dramatic, and it can also result in a lengthy mandatory state prison commitment.

Derek Ewin has spent years studying these laws and their applications.  Mr. Ewin knows what weapons are legal and what are not.  He knows how to legally transport firearms and other weapons.  So, if you have been arrested for carrying a loaded or concealed firearm, a dirk or dagger, for being a felon in possession of a firearm or for any other weapons related charge, Derek Ewin knows your defenses and how to get you the best possible outcome.

Client Review:
I need to share with you how much knowing Derek Ewin and having him work on my case has changed our life.  Derek was always there for both of us (my wife and I) when we needed him no matter the time of day, or the day of the week.
