NEW DELHI: Delhi CM Arvind Kejriwal said that he is an engineer from IIT and know 10 ways of tampering EVMs. “The companies, where chips of EVMs are manufactured, can use virus or bugs or something like that. The EC has no capability to read what the chips contain,” Arvind said in an interview. “Even if AAP wins municipal elections we will continue to demand probe into EVM tampering because it threatens the base of democracy. “Tampered EVMs is a threat to me as well as to you (ruling party),” he said. He said AAP is ready for re-election. “We did not say anything about EVMs when BJP won in Haryana, Jharkhand, Maharashtra,” he said.
