It's subliminal - we see these, sheeple don't really register that they're there, they just know they feel ever more afraid, but don't know why.
Classic stuff this. The mind games played on the public are many and insidious, yet they don't even know it. The symbology in ads, papers, mags - everything. The collective herd can be made to react in a predetermined way almost every time.
Dave Icke calls it correctly every time - PROBLEM-REACTION-SOLUTION These are part of the problem phase, stirring up the reaction. It's ridiculous!
I asked my wife's family about terrorism questioning the danger they perceived. They were all - except father in law - cacking it!! When I explained that, even by gov figures, they had more chances of death by lightning, or winning the lottery jackpot, they seemed to realise terror had been hyped. Not before, though and that's the crucial bit.
We must get the message out - why would terrorists hit civvies? - the real terrorist would hit the rich and shameless, or the politicians of the day, not Joe Bloggs, Joe has no influence whatsoever! Duh! The so-called terrorists (gov) hit the group in which they want to instill abject terror of going out at all. Us.
Just my thoughts anyway.
