So in the first sequence they demonstrated how powerful the bombs in those hunter droids are.... But then later just played around with one in a hospital, potentially risking thousands of lives.

Even the robot suggested doing it outside.

I don't understand why the writers thought setting up the significance of that danger was worthwhile only to wave it away so casually and stupidly.

Also when you detonate the robot things in order to kill someone - don't make them have a five minute timer.

What would be the point of that?
