A Dutch police campaign trying to counteract online incitement aims to let users know they're walking a fine line. So are the police.
In rare instances, Dutch police are knocking on social media users' doors and asking them to be careful writing posts about refugees that could lead to real-life violence and, ultimately, to charges of online incitement.
One example is Mark Jongeneel, a small business owner in the small city of Sliedrecht who tweeted his reaction to asylum plans in his city:
"The college of Sliedrecht has a proposal to receive 250 refugees in the coming 2 years. What a bad plan! #letusresist"
