My hubby is a firefighter whose ground covers the hospital where these ambulances caught fire(were set alight) within their area they have also had 1 police car torched and are worried that they will be next as the 3rd emergency service . they also have the same protocol from what hubby has said re waiting for back up - and it really frustrates me when Joe Public criticizes any emergency service for actually thinking occasionally about their own safety as they too have family to consider. I totally support the lone responder in he actions but also send my sympathy to the family who lost a love one.
