Sorry if posted on the wrong section.
ok can someone help me with this scenario. Fake names will be used.
So lets assume 1000-100000 people join together for a good cause, but that cause, caused the death of 1000+ people they were told it could cause more deaths but they decided to act on there emotions instead of what is logical, the bad outweighed the good by a lot. Now this person named John decides to release the information of all the people who supported this cause, Adresses, phone numbers, name, and a single picture gathered from facebook, keep in mind all this information is already for the public ex: facebook, whitepages etc, but what john did is he organized the information so you could just click on your state/city and find out if anyone supported the cause in your city. Now lets assume Ken had a child and this child died due to the *good cause* so ken decides to use john released information to find out were some supporters live and he kills them. Now john never had the intention for anybody to use this information to murder someone. Can john get in trouble for releasing information which is already released to the public ex: facebook, whitepages etc?
Can john also use the pictures from facebook?
Thanks for your help.
