Main problems:

1. Transnational nature of the crimes. Most policing is local. 2. How much do the police understand the Internet and computer technology?3. Resources and person power are limited – how much time can the police devote to cyber crime?4. What responsibility do the ISPs have/ How can they enforce it?5. How much relies upon word of mouth and people reporting dodgy sites? 6. Are there better methods? Parents careful about how their children use the Internet. 7. Better educate children in safe surfing at school?8. Cheaper to educate parents; use firewalls, net filters and virus software up to date, use safer browsers eg Mozilla Firefox.

How much does it cost to police and prosecute under the different laws?
