If you have been charged with Assault and Battery by Means of a Dangerous Weapon (ABDW) you should know that it is a felony in Massachusetts with a potential penalty of imprisonment in the state prison for up to 10 years or in the house of correction for up to 2.5 years, or by a fine of not more than $5,000, or by both such fine and imprisonment.
For you to be convicted of ABDW the prosecutor must prove that 1.) that you touched the person of another, no matter how slight, without a right or an excuse to do so, 2.) that you intended to touch the other person, and 3.) that is was done so with a dangerous weapon.
What might be of some surprise to you is that any item can become a dangerous weapon. Over my years practicing criminal law I have seen some extreme and not so obvious items used to charge a person with ABDW. The law just provides that the item has to be used in a dangerous manner that could cause serious injury.
