While the Shi'a are the majority, the Sunnis, Kurds, Turkomen and a few other odd tribal groups make up a not insignificant minority, and they, each for their own reasons, were mightily pissed that the hanging happened. Many Sunnis thought the trial was unfair, should have been done in international court, or should not have been done at all, and other ethnic groups were furious that they were denied a chance to look SH in the eye and accuse him. And many faithful, regardless of sect, found the execution in such proximity to Eid simply abhorrent.
You may not see it this way, but Muqtada al-Sadr (who decides when/if US soldiers can come anywhere near Sadr City, and ensures that kidnappers of our people aren't punished or captured) pulled those strings to make this happen on the day that it happened, and al-Maliki was his compliant puppet.
The US has averred ever since the government got up and running that the only reason they were holding Saddam instead of handing him over was strictly for 'security' reasons, and that's logical, given how individuals who are wanted by the Iraqi government can manage to bribe their way through
Saddam Baghdad International Airport (not once, but twice) and escape to freedom with relative ease.
http://www.wtop.com/?nid=105&sid=1015496 It is my belief that this shit has spun well out of control well before this "Fuck You, Sunnis" Eid lynching of the former dictator, and the US just went with the flow, as usual, not realizing the full impact of the Eid start dates because that is what happens when you let cronies make policy instead of country experts. The Iraqi government even violated their own law and custom by failing to get sufficient signatures on the death warrant, but I guess they take their cues on legal niceties from their mentors who helped them set up shop. That said, I don't think these mentors were calling the shots, in fact, everything I've read suggested that the US ambassador tried to delay the execution, and had a bitch of a time getting al-Malaki to even give them the body to hand over to the Sunnis after the guy had been hanged. He surely didn't behave like a US puppet during this hideous event, but he sure seemed to be dancing to the Dawa tune.
If any stupid American paws can be seen on this debacle, they're the long-distance, obtuse, and essentially hands-off paws of Rice and Hadley:

‘US Struggled to Delay Execution of Saddam’
Barbara Ferguson, Arab News
WASHINGTON, 8 January 2007 — US opposition to the hastily arranged execution of Saddam Hussein is slowly emerging with surprising detail of a last-minute battle between top Iraqi and American officials, and even between the Americans themselves, over whether the execution, full of legal ambiguities and Islamic religious sensitivities, should go ahead.
Iraqi Prime Minister Nuri Al-Maliki argued with American military and diplomatic officials to hand Saddam over....This was further complicated by the fact that both US Ambassador Zalmay Khalilzad, and the top American military commander, Gen. George Casey, were both out of Iraq on leave.
For Gen. Casey and Amb. Khalilzad, “the messy ending (of Hussein’s death) was made worse by the confirmation this week that Mr. Bush will soon replace both men...Negotiations with Maliki were headed by Maj. Gen. Jack Gardner, and Margaret Scobey, head of the embassy’s political section, due to the absence.....“Tempers frayed” during the late Thursday night meeting, says the NYT, with Gen. Gardner insisting that Iraq’s constitution requires Iraq’s three-man presidency council approve all executions, and a Saddam-era law forbidding executions during religious holidays.
The NYT says Amb. Khalilzad “even made a last-ditch call to Maliki asking him not to proceed with the hanging. But, Maliki was adamant.....It appears Khalilzad then contacted Secretary of State Condoleezza Rice “and she gave the green light for Mr. Hussein to be turned over, despite the reservations of the military commanders in Baghdad,” notes the NYT, adding that Stephen Hadley, Bush’s National Security Adviser, supported Rice’s decision......once Saddam was over to the Iraqis at 5:30 a.m. “we then had absolutely nothing to do with any of the procedures or control mechanisms or anything from that point.”....It was the Americans who flew a delegation from Tikrit to Baghdad, and back again, when at midnight, Maliki finally agreed to let the body go. ...
