Marek would like Section 110 of SOC&P Act 2005 to be replaced with sensible legislation: http://petitions.number10.gov.uk/PowersofArrest/

Whereas police officers used to have to justify every arrest and be aware of whether or not a particular piece of legislation gave them power, they no longer have to do so. The power to deprive someone of their liberty should only be exercised in the most extreme circumstances, yet young and inexperienced police officers, (and soon, PCSO’s), are being trained that arrest and detention of a suspect is the first option in most encounters with the public. This sweeping power is being roundly abused on a daily basis in all of the 43 police forces in this country and puts you, your wife, husband or partner, your children and your friends at risk of arbitrary action by the police.
