Many thanks - good to show that a valid debate can proceed to benefit of all.
TWOC'd - now thats just a blatant attempt to be ageist - between you and YDS Jon claiming he'd never heard of William Holden!
Taking Without Owners Consent - stealing a car - popular pasttime in the 1980's ( best defence a beige Chevette ).
Having done a quite a bit of time in military circles and with defence contractors there is something of a perverse reverse in terms of lethality - a fully automatic in the hands of an untrained operator is potentially far less lethal than a 6 shot revolver shot with care.
Tanks are available in the states as here - sans the operating main gun. Imposing and terrifying, but outwith the context of a battlefield environment, far less potential lethality than a heavy recovery truck/ van filled with LPG etc.
Hellfire/ Sidewinder/ Cruise/ Exocet - again within battle environment arguably effective. The requirement of suitable programming software, safety interlock programmes and not least a launch platform - whether land based rail system or a small warship - along with required targeting radar/ satellite interlink; massively cramps effectiveness for solo or small group of crazies!
Genuinely I wouldn't lose very much sleep over those.
Despite frantic bounty and buy back efforts by the US, Stingers et al remain available to various terrorist groups, as do 'conventional' weaponry by the boat load. Money is not a major object to such organisations. Yet their weapons of choice tend to be 'black book' improvised efforts.
There are numerous reasons for that - not least counter insurgency measures as much as logistics. But it remains that high lethality products can be produced in a shed with items from a DIY store/ Supermarket - and the knowledge to do so is widely distributed.
All the above is focussing on the object - back to debate above. The issue is with the person. Think of a dedicated individual with practised skills armed with a 308, firing pure target bullets - by example say a stalking rifle of a type very commonly employed by most of us here. Make his rifle single shot and assume restrictions absolutely limit him to obtaining 100 rounds. Place him in a position with height, good view, collateral soft targets and targets. What damage could he do in comparison with a man driving a tank or utilising an assault type weapon?
For me it comes back to the individual not the tool.
