Online webchat unmonitored
If you are under 18, use it only with a parent/guardian's permission.
Do not transmit nudity, sexually harass anyone, publicize other peoples' private information, make statements that defame or libel anyone, violate intellectual property rights, or behave in any other inappropriate or illegal way on Omegle. You may be denied access to Omegle for inappropriate behavior, or for any other reason.” Users of Omegle should also be aware that there is freely available software which can enable the people they are chatting with to record (and therefore save and share) any activity, so the site is not as anonymous as users might think in that sense.
Police monitoring would also be unenforceable due to the global nature of the internet and as laws about behaviour and content vary from country to country.
There would also be an issue about the resources required to achieve this as if the Police were to monitor Omegle then there would be an argument that they would need to monitor all other chat and social networking sites such as Facebook, email, text or instant messenger.
