All speech should be protected to ensure a healthy, open and accepting society, Intent behind statements must be considered.

http://www.legislation.gov.uk/ukpga/2003/21/section/127

This piece of legislation should be rewrote to allow any speech to be permitted without fear of police involvement except in cases of incitements of violence, harrassment or targeted bullying, threats etc. Jokes, bad taste or not should never be illegal in a free society and the very idea of such is repugnant.
