Clever way to do things

That was way to quick n easy it would never work here they would have to fill a JSA first then install a safety harness wear a hard hat and safety glasses probably ear muffs I case the noisy gun went off, nah all to hard just let the bad guys go much easier

I wonder if they got the idea from watching the crims at work

Very clever, unfortunately more show than go, a ladder would keep all the infiltrating team within the protection of building profile and allow a much faster method of deployment of team. Still great to watch as a spectacular - like watching an experienced arborist walk up a tree in similar fashion (feet first).
