I humbly suggest:
1. Decide what outcome you want - survive, save your money at risk of your life, make a statement about your self-image and how you save society.
2. Take action for that outcome. Don't complain if goes awry.
3. Before you posture on your ability to be observant, handle this or that kind of fight - please consider some serious FOF training that explores how you do act under stress and how you can be taken unaware.
If you have proven such ability, then you said document it here - rather than saying you could do XY or Z.
Having done the NTI and several FOF classes designed to put the civilian in some of the situations stated, I am not sanguine about some of the posturing of spider sense or ability.
