Now it didn't say he had the metal detector so why did he have the "digger" ?? And in my personal experience I haven't met a lawyer yet that doesn't own a cell phone. Why if it was self defense or an attack did the "lawyer " leave the scene ??
If the lawyer was at home and work when the IED was placed on the vehicle originally I'd suggest a local disgruntled employee or neighbor (the one across the road IMHO is suspect based on blood spatter discussed in the thread).
Last but not least I have a theory on violence and trauma based on what I have seen in shootings and combat. People who were raised in a very peaceful environment, never had a hand raised against them in their life, no contact sports like football or wrestling /boxing will fall to pieces physically and mentally at the first hint of pain inflicted upon em. If this Lawyer was such a human being then that will answer a lot of the weird actions like riding away, changing his clothes and bewilderment ect ect ....
Tinfoil hat theory says the goobermint beancounter contract lawyer was using the goobermint contractor to divert funds to off shore account and someone was blackmailing the other and wahlahh ! Pigsticker solution # 5.............. There ya have may SWAG !!..............
