Otheruses Lock On disambiguation Unreferenced date May 2010 A lock on is a technique used by peaceful protest ers to make it difficult to remove them from their place of protest. It often involves handcuffs , chain s, padlock s or bicycle lock s. More complicated lock ons involve protesters putting their limbs through pipes containing concrete , or a mixture of steel and concrete and is only limited by the imagination and ingenuity of those making the lock on . The willing protester can choose between a type that will allow them to willingly remove themselves or a type that requires machinery to remove them. The safe removal of the protesters necessitates the involvement of skilled technicians, and is often time consuming. The lock on chosen by the protester may be the difference between being arrested or not, or may vary the kind or number of charges brought against them by the police . If a protester can remove themselves when asked to by the police, they may stand a better chance of not being arrested. However, if they can remove themselves and they chose not to, they may receive a charge for refusing to remove themselves from the lock on. If the protester cannot remove themselves, it is likely that potential charges are not as important to them as what they are protesting about. Locking on is a very successful means of slowing down operations which are in truth or are perceived by the protesters to be illegal or immoral it is also often used to allow time for journalist s to arrive and record the scene and take statements from the group spokespeople.

wiktionary l c The suffix lock in Modern English survives only in wikt wedlock wedlock . It descends from Old English l c which was more productive, carrying a meaning of action or proceeding, state of being, practice, ritual . As a noun, Old English l c means play, sport , deriving from an earlier meaning of sacrificial ritual or hymn Proto Germanic laikaz . A putative term for a hymn to the gods Ansuz ansu laikaz in early Germanic paganism is attested only as a personal name, Oslac name Oslac . Suffix The Old English nouns in l c include br dl c nuptials , beadol c , feohtl c and hea ol c warfare , h medl c and wifl c carnal intercourse , r afl c robbery , w tel c punishment , wr htl c calumny besides the wedl c pledge giving , also nuptials ancestral to wedlock . A few compounds appear only in Middle English , thus Renaissance occultism dweomerlak occult practice , ferlac terror , shendlac disgrace , treulac faithfulness , wohlac wooing , all of them extinct by the onset of Early Modern English . The earliest words taking the l c suffix were probably related to warfare, comparable to the ple a wikt play play suffix found in swordplay . The Old Norse counterpart is leikr , loaned into AB language North Midlands Middle English as wikt laik laik , in the Ormulum appearing as le e . The suffix came to be used synonymously with nesse , forming abstract nouns, e.g. cl nle e cleanness . Noun The etymology of the suffix is the same as that of the noun l c play, sport , but also sacrifice, offering , corresponding to obsolete Modern English lake dialectal laik sport, fun, glee, game , cognate to Gothic laiks dance , Old Norse leikr game, sport and Old High German leih play, song, melody .
