Authoritarian tactics to suppress protest typically intend to have a chain of effects like this:

• protest will decrease
• those who protest will protect themselves better, legally (in terms of planning and considering how to avoid charges)
• those who protest will protect themselves better, physically (in terms of not being detained and overcoming the police)
• in the second scenario, police will then be able to depict the protests as "violent" and call it an "insurrection"
• consequently, they can press heavier charges against anyone they do manage to detain
• organizing a protest becomes dangerous
• participating in a protest will be perceived as dangerous
• people with families and a job and elderly people will fear to participate
• protest will lose effect due to few participants
• that will prompt some individuals to anonymous protest and actual sabotage
• nobody should want that, yet that's where the path leads to

The solutions?

• fixing the problematic laws via political process, adding a freedom-of-protest agenda to other goals
• disputing the problematic laws where the legal system allows (appealing to constitutions, conventions and charters)
• bypassing the laws after analysis, protesting in ways that cannot be criminalized
• in rare cases where it's worthwhile and there is exceptional mass support, just ignoring the laws, because if there's a million people blocking streets for some reason, cops are powerless

All of that won't be doable in every country, and in some countries, something else might be doable instead.
