Personally, I've only ever received jokes an memes that were forwarded...
"until deaths due to fake news have stopped completely" will/should never happen.
You are asking for censorship by state. Not sure how/why anyone would ask for such a measure, instead of asking the responsible state govts in India to improve the Law and Order situation.
When there's is a hint of crime or a need for medical attention, in the US, first thing a person thinks of is calling 911.
In India, first thing a person thinks of is, how he/she can address the situation, because <insert emergency service here> will never reach on time nor be of any help.
Most riots in India flame up due to false news. Whatsapp is just a medium that is super efficient in spreading such false news.
Dont shoot the Messenger/Whatsapp etc. Ask for better reforms!
One of these is not like the others.
The coming wave of technology and tools is only going to exacerbate these problems further.
One small thing that whatsapp could potentially do is to make it a little bit harder to forward messages to everyone. force people to wait a couple of seconds before adding another person.
