As always skip the Decoding/Numerology part if you find it ridiculous, but make sure to read the important info at the end.

DECODING:

Immediately looking at the first image used to present the event: 33 coded (U = 3)
33 Highest degree of Freemasonry and the number of Illumination.

They are not even trying anymore. Supposedly 3 people died in a terror attack yet everyone's laughing and smiling and enjoying the day out (and probably the double pay).

What are the police doing there? because there's a peculiar Orange entrance.
The Brotherhood of Light communicates using Orange as even the Knightfall TV series will tell you.
Orange is the only colour that is 33 in Numerology.

Also I found this image interesting:
113= Order of Malta (Hospitaliers) became a Sovereign Order in 1113
21= 7+7+7 (Order out of Chaos)
The Triangle/pyramid (also in Scottish Rite iconography it is sometimes reversed,"as above so below").

They skipped the Skull & Bones day 3/22( I said it would be too obvious doing it 3 times in a row), but 23/3/2018 a pretty good alternative. Contains both 33 and 322 .
Also 2 dead and 3 wounded on a 23 date= 2323 = 322 & 33.

ISIS is HATHOR

ISIS for those who do not yet know is an invention by the International Hathor Pentalpha Freemason Lodge and other UR-Freemason Lodges for "War abroad and Tyranny at home".
The Skull& Bones Yale secret society is just one of the many recruitment centres for Hathor Pentalpha.
Hathor Pentalpha was setup by the Bush's and has Al-Baghdadi as confirmed member, as well as Tony Blair and many others. Al-Baghdadi is a jewish Mossad agent.

Of course ISIS and HATHOR are also pretty much the same Egyptian deity.
So the clue was always there...
