was being extreme/sarcastic with his statement. If he's being serious well that's his own opinion and not what the public feels they all should do when they see someone behaving indecent.
A summons or community service as you recommend should be implaced but that's only due to the severity of the behavior or crime committed. 20 years for licking ice ice cream is beyond imo ridiculous. But this happen in Texas and imo Texas laws can be ridiculous.
