Reading about Crystal Palace Holmesdale Enders latest artistic banner design.
Apparently the Police are investigating it as they've received an avalanche of complaints about its content which has caused offence.

Article 11 protects your right to protest by holding meetings and demonstrations with other people. You also have the right to form and be part of a trade union, a political party or any another association or voluntary group.
Ive been/helped organise many demonstrations locally & nationally for Mental Health campaigns when in England to promote awareness so know the ins & outs of the laws.

The Palace dig at Millwall fans banner [below] interesting got no Police action or complaints but their 'PL dig' latest banner has now apparently got Police investigating it after numerous avalanche of complaints.

Thought these 2 previous Palace ones were spot on regardless.
