If you have been accused of assault or battery in California, you need to take the charge seriously, even if you did not commit the crime, because the state takes the charge seriously. California law almost always requires the police to arrest anyone, rightly or wrongfully, accused of assault or battery. A misdemeanor conviction could result in up to a year in the county jail. A felony conviction can result in 16 months or more in state prison.
If you have been arrested for battery, assault, criminal threats, terrorist threats, threatening phone calls, damaged phone lines, or intimidating a witness or victim, you need a local criminal defense attorney with the experience to defend you. Often these cases can be dismissed or reduced to lower charges which do not require jail time.
