Willies Mchunu's response to the violent attacks on Abahlali baseMjondolo at the Kennedy Road informal settlement in 2009 was and remains controversial.[8][9] At the time of the attack, he claimed that the attacks were by a "criminal forum" associated with Abahlali baseMjondolo president S'bu Zikode.[10] Abahlali baseMjondolo and many civil society organizations have called the attack on Abahlali baseMjondolo and Kennedy Road residents politically motivated and blame Mchunu for condoning the attacks by an armed group affiliated with the ANC .[11][12][13] Mchunu's response to the attacks was also criticised by Bishop Rubin Phillip and Archbishop Thabo Makgoba.[14] Mchunu refused calls for an independent investigation into the attacks.[15][16] Amnesty International sent a letter of concern to Willies Mchunu, but there was no response from his office.[17]
On 18 July 2011, the case against the twelve members of Abahlali baseMjondolo arrested after the attacks was thrown out of court.[18] The Socio-Economic Rights Institute of South Africa issued a statement saying that the "charges were based on evidence which now appears almost certainly to have been manufactured" and noting that the Magistrate had described the state witnesses as "belligerent", "unreliable", and "dishonest".[19]
According to Paul Trewhela, "The scandal is that this political prosecution was instituted in the first place, and that it was dragged on, month after month, by magistrates, prosecutions and police without a shred of reliable evidence - with plentiful evidence, rather, of manipulation and intimidation of witnesses by the police and local ANC structures."[20]
In last 2012 six applicants for positions as traffic officers died during a fitness test and another committed suicide following which there were calls for Mchunu's resignation.[21]
Since 24 people were killed on 5 September 2013 in one of the most horrific accidents on Fields Hill, the 2013 Pinetown crash, Willies Mchunu has discounted calls from residents for the banning of trucks on the "Hill of Horrors" as it has become known. Local City Councillor Rick Crouch has been vocal about the Provincial Government's failure in stopping the carnage on Fields Hill, going as far as accusing the KwaZulu-Natal MEC for Transport, Community Safety and Liaison, Willies Mchunu, of practicing tombstone legislation.[22] Councillor Crouch has been campaigning for stricter rules for trucks on Fields Hill.[23]
