Hmm, lets see..
1. Irsish guy
This should bring in a good 10 troops. They could be thinking along the lines of the IRA.
2. Shaved head
This is a nobrainer.. a Neonazi IRA member? 13 troops.
3. Nuke symbol in hair
Ehh that'll bring us to 14 troops.
4. Densly populated area
This could signify as a terrorist prone situation. 34 troops
5. Rumored
Well if we go by the DoD's method of handling "rumors" that brings us to 40 troops
6. Mobile chemical sprayer
I'll just throw out a number.. 46 troops
7. In hotel
48 troops.
8. Girl troubles
57 troops.
So 57 to take me down and only one bullet needed. Now, they could also mistake my handle as a secret agent from some radical foreign secret service so lets round it off to 60.
I have way too much time on my hands...
