We were on the Tube on Saturday, arriving at Leicester Square at about 4pm.
We couldn't work out why it was so crowded.
Then we remembered, it's London. The Tube is always crowded. Especially in the Central Area. Especially on Saturday afternoons.
I saw no police. No avoidance of supposedly suspicious looking Asian men (actually, not sure if I saw any supposedly suspicious looking Asian men) and no staring jumpily at stray or abandoned bags (dunno if I saw any bags).
