Is it an offense to attack someone with a toy water pistol?
<p>If someone started yelling and swearing at you on the bus can you pull a water gum and spray water in their face? or maybe do it with a bottle of water. </p>

<p>Would you get arrested for that? </p>

<p>It would be a crime and a tort.  Battery.  If you touch a person with something you cause to contact them rather than with your fist, for example, you have still committed the crime and tort.  </p>

<p>I remember reading one extreme case where I believe a tortfeasor was found liable (i.e. it was a civil case and he was sued and had to pay damages) for battery for blowing smoke in someone's face.</p>

<p>There may also be some creating-a-commotion or having-liquid-on-the-bus-without-a-lid or other random laws and rules implicated in your example.</p>
