Act must be considered dangerous on an objective basis
Church defines this as 'an act which a reasonable and sober person can foresee as causing some harm not serious harm'
JM&SM - no need to foresee specific type of harm
Danger can be aimed at someone else (Larkin) or at property (Goodfellow)
Watson - burglary can be dangerous if V's fragility can be seen
Bristow & others - can be dangerous due to specific circumstances
