Attempted murder is about the hardest criminal offence to prove, as the jury needs to be sure that the defendant intended to kill the )non-deceased) victim, no such intent to kill being required to prove a murder to the prevailing standard. And the alternative for juries is always s18, which has a maximum sentence of life anyway. It’s not like an acquittal based on a failure to prove intent to kill means a walk out. Anyone guilty of s18 as an alternative to attempted murder is looking at a starting point of fifteen years, will serve ten. That’s a long stretch.
Nothing in that clip looks remotely like attempted murder, but Brazilian law will be different.
Still a bit nuts, though!
