Homosexuality Leaflets Arrest

[nailit]

Didn't know whether to post this in law or religion, so did the obvious...and put it in chatterbank!
Story from my local paper. A man has been arrested after posting anti gay leaflets through peoples doors. The leaflets are of a religious nature stating that homosexuality is a sin and unnatural.
The question is why would the police arrest this man when Ive had Watchtower and other religious magazines/pamphlets given to me that state the same thing.
Also various religions also teach against homosexuality without anyone been arrested. http://www.stokesentinel.co.uk/Man-53-arrested-distribution-anti-gay-leaflets/story-22907391-detail/story.html
