Generate text that refutes this claim: An ICC enforcement arm is unnecessary  To create an enforcement arm for the ICC would be to accept that state parties are incapable of enforcing decisions themselves, that is not necessarily the case. State parties have supplied the ICC with many of the defendants that it desires to face trial, including Bemba and the Gbagbos. Some, such as Uhuru Kenyatta have appeared voluntarily. The current system is working in many cases. While it does not in all, there are some that will be extremely difficult to capture by anyone.
crime policing international law house believes icc should have its own enforcement
An ICC police would be able to provide independent assistance to these states to aid those that do not have enough resources. The ICC has a poor track record of capturing suspects. This is not due to a lack of trying by the ICC – in some cases, it is due to the lack of trying of states such as those that have played host to Omar Al-Bashir. While individual states do, and should, have a role to play in enforcement, in some cases they are unwilling or unable to arrest suspects. Just as the ICC is there if a state is unable or unwilling to try an individual, they can have a role if they are unable or unwilling to arrest them.
