Sharma's comments did result in violence. The Supreme Court blamed Sharma for inciting a beheading that was carried out by extremist perpetrators:
> The Supreme Court Friday slammed suspended BJP leader Nupur Sharma, for her controversial remarks on the Prophet. While hearing the plea filed by Sharma seeking transfer of the FIRs against her to Delhi, the Supreme Court accused the leader of “igniting emotions across the country” with her “disturbing” remarks.
> “She has threat or she has become a security threat? The way she has ignited emotions across the country. This lady is single handedly responsible for what is happening in the country.” “She and her loose tongue have set the entire country on fire.”
> The Supreme Court said her outburst is responsible for the unfortunate incident at Udaipur, where a tailor was murdered.

As for Kajal Hindustani, it looks like her situation is being handled appropriately:
> Police have registered a first information report (FIR) against a woman activist for her alleged hate speech and detained more than 50 people on the charge of rioting following a communal clash at Una town in Gujarat’s Gir Somnath that left two persons injured, an official said on Sunday, PTI reported.
> “We have registered two FIRs. One is against Kajal Hindustani for hate speech, and another against the mob for rioting," Superintendent of Police Sripal Sheshma told reporters.
