Final answer:
To reduce the possibility of fights between rival fans in the future, post-event steps like increased security presence, relocating the teams, and banning rival fans can be taken.
Step-by-step explanation:
After fights break out between rival fans, several post-event steps can be taken to reduce the possibility of this happening again:
- Increased security presence: This involves having more security personnel in and around the venue to deter and quickly respond to any potential conflicts between fans.
- Relocating the teams: Moving the teams to different venues or separating them in the stadium can help minimize the chances of direct confrontations between rival fans.
- Banning rival fans: Temporarily banning rival fans from attending matches can be an extreme measure taken to ensure the safety and security of both fans and players.
