Roberto Laudisio Curti (died 18 March 2012), known as Beto Laudisio, was a 21-year-old man from São Paulo, Brazil. He died on 18 March 2012 after being pursued, tackled, tasered, sprayed with OC spray, and physically compressed under the weight of multiple police officers of the New South Wales Police Force in Sydney, Australia.
Police officer attempts to take down resisting suspect with armbar, a technique commonly taught to police in many countries. This results in the officer failing to control the body of the suspect, and falling beneath him into a dangerous position. Luckily his colleague was competent and timely with the TASER.
Reluctant to go hands-on, police use their baton, then Taser which fails multiple times. One police officer attempts to knock over the man by rushing at him from behind but ultimately loses control as he stands up. The Taser is used again, then OC spray before the Taser is used once more before the man is taken into custody.
All of the tools police used in this instance depend on pain compliance, apart from the Taser which incapacitates for mere seconds IF the two prongs make contact correctly and in the correct positions on the body. Physical control with grappling techniques may have resulted in a faster and safer arrest, however these officers either lack those skills or were not willing to go hands-on.
A physically outmatched police officer attempts to use Taser and baton. A second police officer arrives and shoots the man.
A man with two knives attempts to stab a police officer. Due to sheer luck, he did not attempt to stab the officer anywhere except the stab-proof vest he was wearing.
A taser was deployed very little practical effect.
