>Are you suggesting that writing explanatory blog posts about technical topics is dangerous because someone will eventually come after you for being elite?

Yes, based on my personal experience and that of others. But I wouldn't call myself elite... I just know a little bit ;-)

I am saying giving them any sort of heads up is not good praxis, since the police have so thoroughly abused the access they already have.
