I dont have a problem with this. Provided they meet their obligation to ensure an appropriate response.
Personally, I have performed the roll of duty officer remotely. Sometimes it has worked well, sometimes not. On the times that haven't, the truck still rolled even though a default had been requested. So, more trucks than less. Not perfect, but not an innapropriate response.
These defaults have happened anywhere from approx. 8 minutes, to a maximum of 15 dependent on the type of response.
All comes down to the process put in place at the local level.
Cheers,
