Hi Sean.
Long time, no see, etc. 
In response to your baited question, it should be readily
apparent -- this is a simple exercise in reasonable deduction.
LEA's want to have the same technical capability to wiretap
communications in technologies where they currently do not
posses the capability to do so.
Pretty straightforward, really. But the technicalities are
hornet's nests. Vespas.
