What makes you think police are better informed/educated than fire fighters?
The reason they told people to stay put was due to learning from other incidents where stampeding/panic was more dangerous than people waiting to be evacuated In an organised way.
On this occasion unfortunately it turned out not to be the right decision but it wasn't made lightly as you seem to be making out!
You don't and never have lived in a high rise, you ever been in a fire? Or terrorist attack? I have. People don't react sensibly, they panic, they get lost, they wander into hazardous areas...
Personally I think everyone should be taught first aid, how to get out of a building on fire, how to react in certain terrorist situations.
Having loads of people wandering about, heading to where the fire/smoke is worst, panicking and hoardes trying to all run down the stairwells at once - recipe for disaster.
Grenfell absolutely was a tragedy but who's to know if more people would've died, been seriously injured if they'd been "every one for themselves"?
"it's better to chance it and get crushed, rather than to stay and risk it? (Genuine question)!" Wow! The ignorance! You do know crushes can kill? Result in spinal injury?
I strongly recommend you get some first aid and emergency situation training.

Flyingpompom you would be SO irresponsible to ignore the way you've been trained in fire drills, we have fire drills precisely to reduce panic, the idea being that that the training overrides wrong instincts.
Instincts aren't always right.
