On the second week of testifying, Wong admitted that he proactively asked Ng for firearms to be used in a protest that December, even though his team, comprising about 10 “valiant” protesters, had agreed not to touch firearms or use explosives.

“Our team had reached a consensus that we ourselves would not touch firearms or use explosives,” he said in the witness box.

“After Ng said he would give me two guns, I did not think thoroughly about our consensus.”

Wong was testifying against his alleged team members, including Cheung Chun-fu and Cheung Ming-yu, who were among six defendants who denied a joint count of conspiracy to plant the bombs. Both Wong and Ng had earlier pleaded guilty to the same charge.

The prosecution had said in an opening statement that the key to determining the culpability of the defendants was whether they had made “an agreement” to partake in this bomb plot.

Last week, the court heard that Wong only informed his team about the December 8 plan days earlier.

A Telegram chat record between Wong and Ng also showed that the former had another plan that involved using firearms and explosives in a protest on December 1 that year.

In their private chat on the encrypted channel, Wong asked Ng if the 20kg (44lb) of explosives – which Ng claimed to possess – was ready and whether Ng could give him two guns.

A separate group chat of Wong’s team displayed at court showed that Wong proposed to put bombs near Langham Place, a shopping centre in Mong Kok, which he thought was the best spot to attack most officers on December 1.

Cheung Chun-fu disagreed and raised concerns over the danger it would pose, as many high-rise buildings were in the area and innocent civilians would be harmed.

But Wong replied: “Our target is to bombard as many [officers] as possible. As long as we achieve this purpose, I do not care about the others.”

Mrs Justice Judianna Barnes, presiding over the trial, asked Wong if he planned to wilfully slaughter the innocent. Wong said he indeed did not care at that time.

Wong added he eventually called off that protest because one of the team members was unavailable and he did not have an escape plan yet.

Thomas Iu, Cheung Ming-yu’s defence counsel, questioned Wong’s motive of killing police, based on evidence suggesting that he was offered more than HK$1 million (US$128,000) by Ng if he succeeded in the plot and fled to Taiwan.

“Did you want to kill because you were greedy for the money offered?” asked Iu, an allegation Wong denied.

Iu said although his client was the only one from the team who had attended a military training in Taiwan in September that year with Ng, that camp itself was not at all serious.

Iu pointed out the training was “not the slightest” related to the bomb plot because Wong and Ng had not even begun to plan anything at that point.

Iu also showed the court a chat record between Cheung Ming-yu and Ng after the training, in which the former made it clear that he would not want to be involved in a police assassination.

“I do not think I am the candidate if [the social movement] reaches a point where we have to consider [killing police],” Cheung wrote in a message.

The hearing will continue on Wednesday.
