Wasting our TV LIcence fee

What is the point of sending a corrrespondent, and a sound and camera crew, to stand outside a location where a story is based, BUT NOT ACTUALLY HAPPENING!?  Yesterday we had a poor lady freezing her bits off outside No 10 Downing street, at 10pm, to tell us what had already been reported earlier in the day.  I suppose we got to see the PM’s cat, live.  Really useful.  Well done the BEEB.
