Honestly everyone is shocked by how Luffy got this far, but once the big guns came out and the riots break out at level 2, level 4, and the main entrance simultaneously, you have to presume that its all downhill from there. Do you think any prison in the real world can contain a riot of the combined force of all its prisoners?
As pointed out, the security at Impel Down is realistically as good as it could get. Any other day, even this level of riot could could have been easily contained by the forces at Marinford right next door. However, the timing couldn't be worse.

I am not sure what kind of enemies some people are expecting Luffy to run into. This prison, along with Magellan and his lackeys would be enough to keep even the strongest criminals in captivity, as long as they didn't all break out at the same time.

Also, why would anyone expect Luffy to end up fighting the strongest criminals one by one. Unless Luffy freed them himself for the challenge, they should still be locked away.
