Continuity mistake: When Blake is talking with the orphan on the bench, the wider shot of them shows the fence behind them being totally still. But in the shot of the orphan saying "Do you think he's coming back", the fence is suddenly in the middle of rattling in the wind. (00:18:55)
Continuity mistake: When Commissioner Gordon and his men are caught by Bane's henchmen and sent to exile, Bane takes Miranda away, but then Bruce speaks to her before leaving with Lucius, and then asks the commissioner where she is just scenes after. (02:03:54 - 02:07:05)
Other mistake: The cops charge Bane's army, who are armed with automatic weapons, and yet only a few of them fall as they run towards each other. The cops would have been mostly cut down before they got anywhere near Bane's troops.
Continuity mistake: When Selina Kyle and Daggett fall onto the elevator, the shot cuts away before Kyle gets up. Yet in the following shot, she is fully up and standing within range of the cables. (00:52:25)
Revealing mistake: When Bane first breaks into the stock exchange, he forces one of the guards into shooting his gun. Two mistakes: there is no flash or muzzle flare, and the gun has an insane amount of recoil. It's not a cannon, it's a 9mm. It's also not the guard being startled by Bane: Bane is the one holding his arm.
Continuity mistake: During the raid on the stock exchange, watch as Bane snaps the man's neck and slams his head on the table, you can see without placing his finger on the print scanner, but it appears there on the next shot.
Visible crew/equipment: When mercenaries arrive on the stadium stands, there is a visible vertical black edge of green-screen panel at the bottom right corner of the screen. (01:30:25 - 01:30:30)
Continuity mistake: After Batman and Selina escape Bane's men on the roof-top, Batman flies with Selina in "the bat" and drops her off before returning to the batcave. When he arrives in the cave, he emerges from "the bat" without his mask on and examines the data he obtained from the stock exchange heist. At this point he should still have on the dark black eye makeup he typically wears under the mask, even without the mask on. We are to believe he returned to the cave directly after leaving Selina, and it would not make sense that in flying back home he removed his face paint. (00:55:45)
Audio problem: When Batman meets Catwoman in the tunnel to meet Bane, her lips don't move when she talks, then her lips move when she is not talking.
Continuity mistake: Towards the end while Bane is fighting Batman, he breaks a column, but in the next second it is intact again.
Continuity mistake: When Hines Ward scores the opening touchdown as the field collapses, he ends by the letters "ues" (end part of Rogues). We see the field collapse up to the lettering, including part of the "u." When the mercenaries storm the stadium, there's a wide shot of the end zone and more of the field is present by those letters. Plus, when Ward is in the end zone, the grass is green between the letters, but in wide shots, the grass in the end zones is painted yellow with black letters.
Continuity mistake: During Bane's first fight with Batman on the catwalk, when Batman catches Bane's left punch and then headbutts him, Batman's right hand is in the air and not holding the ledge. In the very next shot, Batman's right hand is now on the ledge. (01:12:10)
Continuity mistake: In Bane and Batman's second fight scene, before they walk up the steps, Bane side kicks Batman with his right leg. Immediately after that, in the next shot, the angle changes and he kicks Batman with his left leg, instead of his right. (02:14:50)
Audio problem: After Bruce escapes from the pit, he and Selina talk under a bridge. Bruce says "I admit I was a little let down" but his lips aren't moving. (02:01:17)
Answer: He was about to admit Harvey Dent is responsible for multiple murders, but he realised that would end his career and probably bring back the old days with the mob and gangs running wild. Even though indirectly the Joker was responsible, the public would still see Dent as a murderer and still cause the system to collapse. Batman was able to be blamed for the murdering Dent and those other people instead of the Joker, who was already in custody and couldn't have killed Dent.

This question is about why not just blame the Joker for all of the deaths. Not why he chose to never tell people that Harvey Dent began killing people.
Because it was easier to blame Batman for all the deaths, since he was being blamed for Dent's death already.
