http://www.gwentpa.police.uk/pa/agenda/SPPC14thJanuary2010/item%205c%20appendix%20lpp.pdf - Gwent Police - emergency response time goals of 15 minutes in citys and towns - 20 minutes in rural areas - 10 seconds to pickup the 999 phone
http://www.southwalesargus.co.uk/news/8262617.Gwent_999_call_time_target_is_hit/ - ambulance reaches 60% of emergency calls in under 8 minutes
If it takes 15 minutes to respond, does it really matter if the 999 calls are answered in 10 seconds?
