No kidding! Courtesy of SatD, again:-
By-Law 4. Offences. No person shall, unless approved by the Commissioner in writing, in the Dataran Merdeka ...
(o) erect any tent, booth, shed or other structure;
(r) lie down or sleep in any part of Dataran Merdeka; or
(s) allow any animal which is under his control to enter or remain in any part of Dataran Merdeka
You may not want to respect the law, but at least know what the law is.
To stop being ignorant, refer to the full by-laws in The Setingarden: Evaluating "The Occuption" and the planned "Sit in". (... and leave your comments there, please)
